Loving just the genuine feeling of being back in a workshop. I am a mechanic but have been stuck at home for 2 years since becoming disabled. Love nothing more than talking nerdy and sticking my head in a job🤘
Me too. It really effin sucks.
Who needs football, when Ricky rants, fbs & humour is thoroughly more entertaining 👌🏽
I do love the tour through Ricky’s accents…a genuinely witty and comedic chap..pricelessly irreverent. Davlar is good value too as foil to Ricky’s amusing output, as he works.. (I’m getting Welsh Valleys, British Sub-Continent, Yorkshire, British Upper Class (“Dear Boy”), David Attenborough and more..).
Should show this clip every time some 🤡 says you just plug a laptop in and it tells you what is wrong.
B7 RS4, like an R8 for your family. Such as soft spot for these.
Love watching the fault finding! Being local I can also relate to your test drives, around Hawksworth, Oasis and Great Western way. Keep up the great work Ricky.
Loving these one car diagnostic and fault finding uploads
Just watched the video of you dynoing that RS5 that's gonna be raffled, top man for doing it for free cause it was a good charity. Credit to you sir!
Bloody hell, sorry Kate, I'm slipping. Hiya 👋 😘😘 gonna take another bunch of flowers now, lol 💐
Ooof B7 content. Been thinking of bringing mine to you for some love
I love watching a man with a passion that knows what he is doing
Another great video I think these kind of videos show how good you are at your job
Keep up the good work
Loving the refresh direction you guys have taken. Keep em coming!
Friend had problems with one of these (2007 B7 Avant) on lease from Audi UK …on delivery from new EPC light would randomly come on intermittently anything from a few days to weeks (50% time when light load sat cruising on motorway)…very odd. Engine was stripped and few things remediated like cracked vacuum hose etc but EPC problem not resolved. Was in the shop for a few months testing and ultimately didn’t solve the issue. Other problem was ESP taking power off on moderate/hard cornering…talking to guys on enthusiasts forum it was solved by disabling ESP stage 1 (when dry) - saloon variant seamed less prone to this problem so we figured firmware physics tables probably over cautious on avant 🤪 Friend was offered the car end of 3yr lease for a song but sent it back instead 😵💫 Aside from that amazing car… the 2nd stage induction and rev ranges were insane fun but stopping every ~160 miles for fuel not so much 😎😂
Keep doing this, really enjoying the investigation work and seeing the solution. Shame we could not see the solution in this episode.
I think they said they will be doing a second video in the next coming days so maybe this video will be the fix
Great Saturday morning in Australia when Ricky uploads video love it
Same happened on my S3 .. crank sensor went and was horrible to drive .
Great video Ricky , Love this man, i had a B7 RS4 and 3rd gear is mega, it goes on forever
I admire your honesty, I haven’t done anything, couldn’t be further from the truth, unpicking past failures is no mean task. It also helps if owners /customers are up front with history, brilliant, good luck with the new premises
Karl is looking very realistic in the background 😂😊
I kept with it till the end and boom 🤯 have to wait till part two to find out if it’s fixed 😂 love watching your uploads great content and just a bit different than most normal channels down to earth no bullshit saying buy this and that and makes me laugh , cheers
Thank you for this video and your time and effort making this vid. I'd LOVE an RS4, but they are a super car and need looking after, oh boy I don't have the funds.
You're right about using genuine parts. I've had to return aftermarket part because they were worse than the failed part!
Keep up the great work and good luck with new shop
Thanks 👍
I'm going for carbon build up on the valves
Leaky toobs and intercooler or a crank or cam sensor are the other candidates.
Oh he just ruled out the toobs though mass airflow he says looks proper
I have had a jolly good time finding out that I had a split (literally) hose somewhere in my vacuum/boost circuit that would only leak on pressure difference. Smoke didn't find it, I had to take things apart and inspect them before I found the root cause of this car. Mind you, I bought it for next to nothing because three workshops fired the parts cannon on it for two previous owners and it took me over a day to solve it, *after* I undid all the butchery and chinesium parts that were thrown on. It could be the things Ricky said on the end of the video, but if not, look for the hose/pipe that only leaks under actual pressure/vacuum.
My very rare green B7 RS4 Avant is up for sale, lovely condition and runs like a sewing machine, see it on Pistonhead
She's a beauty!
She’s a beautiful example
@@ShalomBrother Thanks
Had a stuck wastegate on my RS turbo in the 90s and ran like shit under full load. Took it to my Ford dealer who took it out and stuck the conrod out the side of the block. All the engineers mulling around when i came in and they said they hadnt driven it at all. Luckily I always log milage when I leave my car somewhere…
I took my RS4 and modified it heavily. The valves were replaced with Mary Quant 2CV6's, Terry and June camshafts. Fitted a dry sump system made from a royal Dalton toilet cistern. It took the fire service four hours to put the fire out. It left a bigger stain on the M6 than a Tesla.
Having similar issues currently with 08 S6 v10, but only at idle. Battery died, then car developed small kinda back fires from driver's bank. New MAF sensors and now does it from both banks. This is actually a somewhat common issue with double ECU engines from Audi usually after carbon cleaning...
Ironically there is a tsb from Audi for this issue on double ECU v10 R8s and the remedy in the tsb is to update the firmware on the ecus to correct problem...
I am actually taking out all 4 VVT solenoids to resistance check and clean them. In my instance these make sense as after carbon cleaning I never removed and checked these... Wish me luck.
watching this video as I have an RS4 B7 so interested how you fix it ( just in case :) )
Top Technicians Great Thanks 🎉😊
Hi Ricky, I spoke to you a few times on insta, love the vids keep them coming. Question....Ive got a bmw m2 and am taking it to the nurburgring at the end of the month. What brake pads would you recommend putting in it? It's got oem atm and could do with being changed. Im going to do the usual service and tyres etc too
Just watched Shifting Metal nicely handled by Ricky 👍
is the coolant temp shared between the 2 ecu's? ive had vag's run like crap because of bad coolant temp sensors
Tunes will be the death of us. The lessons have not been learned. Most tuners defeat the engine protection features to squeeze out a little more power. If you're lucky, you just pop a head-gasket. In other cases, you hammer your ring lands or cook your pistons. It's a mess.
Yesss Ricky and Dav... Fixed my issue on a same era Audi, unplugged runs so much better 😂... I thought it'd just identifed as a firework on boost
I'll get you both a pint if ever I see you 😄
Audi Recall still outstanding on this car
Gives a great impression, and would fill me with confidence in leaving a car with these guys. Subscribed
Thank you
I have to ask. Why didn’t you use a scope to test the MAF sensor? Nice and easy test, it’s analogue. Peak voltage should be approx 4v
I laughed at the anti-lag joke more than I should have. Is VCDS sort of the go-to for the normal person for VW/Audi/Lambo/ etc? Seems a lot easier (read: cheaper) to get a hold of than ODIS. Cheers for another good one, Rick.
Yes, VCDS is the go-to
The coolant temp sensor is also common between ecus
If you buy one of these, get one that has not been pissed about by people looking for more horse power. Very little gone wrong with mine.
I had this, was chasing a rich off idle bank 1-2 on my b7 rs4 again a aftermarket bosh maf was found to be the culprit between 2-3k would wobble but not to the extent of this 👍
Do those have Cam Followers like the Turbo'd version?
Could it be the downstream o2 sensors. Are they unplugged or cheap aftermarket garbage. I had a car running super rich turns out the after cat sensor was not in the pipe. It was plugged in and stuffed up in the heat shield.
Very enjoyable as always 👍
Glad you enjoyed it. Thanks for watching.
that HMP wandsworth reference got me lmao
That’s how we do it in Wandsworth bruv!! 😂😂
I had the cabriolet version here in Canada...what a finicky thing it became in the end.
Love this. Thank you.
Glad you enjoyed it! Thanks for watching.
Audi's - as you know so much better than me - use the flow of air, to decide how much fuel to inject. I think this is a MAF sensor problem, and also with the exhaust being filthy, I'd be looking at the condition of - or if there even is - a DPF.
Never seen an RS4 with a DPF
Spotted a lovely e60 5 series in the background 👀
Hi Ricky, I emailed you the other day about Carley going to a subscription model, do you recommend any other software that isn’t subscription.
Also, Audi TTS 2010, second hand headlight fitted, now both Xenon headlights don’t work, DRL’s do still work. Does the new Xenon need coding to the car (base level set etc), then both will work again. I could always fit the old control box off the broken headlight, would this then fix the issue.
Final question, can you reprogram the Haldex to give a more traditional 4x4 experience, i.e. power to all wheels all the time, rather than the front wheels are slipping so bring in the rear wheels just until the front wheels stop spipping?
Love the videos, hope they pay dividend as I look forward to them, especially like the engine builds and fault finding ones.
Thanks Marty
I touched your leg. Oh young man did you really. Sir!
When you put the smoke up the exhaust it was exiting throttle body when you applied throttle.
24min 34sec.
Not sure how you edited video as in whether smoke was still being sent up exhaust at this point.
Would that suggest that there's a valve issue allowing air to cross from exhaust and intake?
How many FPR's do they have? Small leak ?
Yep, I like these ‘let’s find out wots wrong’ vids 👍
Dont these suffer with carbon build up on the swirls?
It's broken that is. But you will fix it. So... if the air mass sensor reading is breaking down and both ecu's use the reading to tweak the fuel demand, why would it be different across the two banks if that measure is used for both fuel pumps that as you say are effectively working as a single fuel pump? I don't understand how one bank would have an incorrect fueling. Hope that makes sense... I know what I'm trying to say. Maybe one Lambda is faulty..... or a broken valve spring😂😂😂 great head scratching video.
Question….
Why are all the R8 manuals for sale in the UK all spyders?
Interesting that they use LS throttle body’s /ac delco
I see the issue, if you look on the front, just below the bonnet.
It has those four circles.
Theres your issue.
In all serioysness its usually the intercooler pipes and clips and a worn out plastic intercooler connection tooobs,
Is it not throwing any codes
When you have eliminated the impossible, whatever remains, however improbable must be the truth 😀👍
Nice watch 👍
Thanks 👍
In the next 5 years, VCDS may be needed to refill the Windscreen washer fluid.
If they weren't such money pits I would love one of those old B7 RS4. What a good looking car.
Q: how do us fans get merch? Also. I reckon a t shirt for Ricky titled ‘#mysoginist’ would be appropriate for him 😂😂😂
No chance that’s happening 😂😂 also merch is sold through our website. Thanks. Kate.
if my car gets choppy it's been because of a problem around the air intake
Would have laughed if at doggers roundabout some bird stuck her arse through the window and said “diagnose that”! 😂
Hi Ricky.
Did the MAF fix this issue?
Patience friend….part 2 is coming! 😂
Very good. Got the same symtoms on my rs4 avant. Happend yesterday@@REPerformanceUK
How's comes your so clever dear boy are we going to see Kate in her mack or is it only fans haha dear boy love the videos so interesting good luck with the new unit
Well with the weather as it is she is in it everyday! Lol
Lol when will the nissan skyline be finished
Rick has anyone ever told you you look like a Poundland Tom hardy 😁👍🏻
He’s gonna rant about that bud
😂😂😂
When the car is adding 25% fuel this doesn't mean something in the closed loop fueling is at fault. Step one should be does it need the 25% (or maybe even more, because +25% is the short term limit).
It almost seems like low pressure fuel pump issues, but im skeptical because your long term fuel trims weren't too bad.
Given both banks are adding near enough to the same amount under load then i would rule out oxygen sensor reading wrong.
I would log lambda control both banks and lambda actual to see if the 25% additional is enough to meet its lamda target.
Another little side thing to check is someone hasn't mixed the oxygen sensors up when doing the downpipes, seen people mix banks and cause dramas doing these
If you swap probes one will go +25% and the other -25% as they wind up the closed loop control.
I went to the MOT station to check exhaust output to see if the +25% was achieving lambda aim….if so then it’s air control or fuel pressure.
It’s not, it’s at .86 lambda so now we have a measurement problem.
@@REPerformanceUK it's weird it has pretty normal long term trims, unless you cleared fault codes
Long term mean nothing as it’s a huge average. It’s short terms that indicate an issue.
In your next video can you call Kate from the office to say hello to Terry crane I've got more chance of winning the lottery lol as I have watched every video you have ever done i think that deseveres a rep tuned uk or fixing broken sh-t teashirt gotta try lol
Thats the first time I've seen Ricky with dirty equipment....
If you can't afford to put the right parts on, i.e. genuine Audi or proper OEM, i.e. a supplier that actually makes stuff for the car manufacturers not just " OEM Quality" whatever the eff that is supposed to mean - often not much - then sell it an buy car you can afford to run.
Ricky…. Great video ! Btw……. I would have thought the only videos on your laptop would have been from Kate’s OnlyFans…. 🤔
Fouled plugs
Wouldn't have been worth cleaning the MAF sensor while waiting for the replacement to come. Just to see if that would have made a difference?
Never does...i always try...but never does.
Guys, you need to edit this and re-upload it without doxing a load of customers names and email addresses.
Anthony, Russel, Oliver, Warwick, James, Michael, Kevin, Rob, David, Chris, Mark, Nigel and Trevor will thank you.
Not sure what part of the video you are referring too?
@@REPerformanceUK I can't point it out easily without drawing attention to the doxing. but you might ask yourself how I know those are all the first names of customers you keep in a spreadsheet. 😉
@@MrSonicAdvance Mate i have no idea what you are on about? Maybe drop one of them an email and tell them what i have done so i can find it!! lol
@@REPerformanceUK I see you found it at the 5:38 mark and have blanked them out. 👍
@@MrSonicAdvanceyes thank you mate!! Took me ages to find lol
What's wrong with it? Its an Audi......simple.
it is wrong because it is audi
Wouldn’t ever get any of the problems on a Lexus V8. Buy Japanese and save all the ball ache and cost….Simples!😉
It's just a boring, ordinary, hardtop saloon car. That's the main thing that's wrong with it.
Yeah cars are great when they are working but f..k me when they ain't ball pain for sure my classic mini failed its emmisions test it was off the scale the guy that did the test said Elton john would be jealous because it was so rich anyway I checked every sensor checked for exhaust leak and turned out it was a tiny rubber pipe inside the ECU connected to the map sensor that was leaking how did I figure this out you ask very simple just sucked on the vacume pipe going to the ecu my tongue didnt stick to it bingo yip gotta love cars 🙈
Do you ever look at historic fault codes to try and work out what the ecu is or has been unhappy about, keyboard mechanic i know but I never saw you do it.
Be nice to know if there was an issue that the MAF was changed for, or if it was changed for this current issue as well.
As tucked down there as a Thai ladyboy…
This was a tough watch guys! Not the greatest content. I’m giving you this info as a fan and want the channel to absolutely light up. This however isn’t the way. Two videos on a lumpy throttle? Really!
