FWIW, I just did this on my 2008 stock C30 on ramps and used the OEM Pierburg Turbo Solenoid Valve (7.28197.16.0) Here's some helpful tips: - I did *not* have to remove the charge pipe. There was enough space to reach up and unclip the tubes to do the replacement. - You can reach up from the bottom as this video shows, and also in from the side just above the axle at the same time if you need to use a second hand to hold the TCV while disconnecting the clips. -Since there's enough space to work, I suggest you disconnect one hose at a time then connect it to the replacement TCV before moving on to the next hose. This way, you're sure to connect them properly without having to worry about markings. Time: 2 hours. Savings over shop estimate: $225.
Man, I wish I had remembered your tip to remove the plastic piece at 5:15. I upgraded my TCV and getting to the compressor inlet fitting was time-consuming and frustrating. Had I remembered your tip it would have made things so much easier.
Thanks for the great video! I did a TCV on a 2010 V50 T5 AWD R-Line today took about 2 hours on ramps. If your doing a AWD vehicle there definitely a little less space due to the take-off for the AWD. Get some long like 12" needle nose and have some patience getting the little spring clamps off.
2005 V50 T5 AWD with 126k. Just installed TCV upgrade from IPD. Was slow to accelerate, shifting was off, terrible gas mileage, turbo was cutting out, etc...No codes, everything else worked great. If you're DIYer, give yourself an extra hour or two to do this job if you're not using a car lift. Space is tight! Curcial tool: Small, angled long nosed pliers, gloves to protect knuckles. The last piece of pipe that sits right on the turbo was stuck. Did not want to tear it, so I did the job with it on, which gave me even less room. If your car is stock, you will not be able to get one of the hoses on IPD's unit without adding length to the hose. I was running out of time, so i just zip tied it to the bracket until I have more time and some extra hose. Another issue with IPD's design is the little rubber/silicon sleeve that goes over the bracket. You really have to push hard to get IPD's unit to go down the sleeve and lock in between the two little notches on the bracket. I installed the unit on the bracket with the sleeve first before realizeing one of the hoses will not reach. It's a lot easier to Hook up your hoses first then install into bracket. Ours looked like the original unit from Pierburg/Volvo. Lasted 122k. Once installed, follow the programming/memory procedures from IPD and it should work like a charm. I don't think I followed it exactly, because I didn't use a boost gage. If you want to be more precise, do it on a deserted road and use a boost gage or a boost app. Or, you could have a volvo tech adjust things for you. Car drives great now!
Thanks for this tutorial ! I will be replacing the original BCV in my own '08 C30 T5 now . . at 120,000kms now there is a big drop-off in power that is quite noticeable during overtaking semi's . . so the plastic BCV is the most likely culprit after noticing the split condition of your's ..thanks again ! : )
Just did it on my V50 T5 125k miles. I experienced lack of power at low RPM, Turbo was only “working” above 2,500 RPM (and not as good as before), lot more engine break and lower mpg (always below 23mpg for mix highway and city driving mix (mostly highway). Power is back now!!!
Actually, I think it can cause underboosting at low RPMs as well, if it's leaking vacuum into the turbo control arm. I noticed that I have better boost in low RPMs when the valve is disconnected, meaning no vacuum to turbo control arm. I changed the valve and it has definitely improved.
Hi. Your content came at the perfect time. Not sure if you can provide any guidance but here it goes. I just purchased a 2011 Volvo C30 and the guy told me that the engine light was on and sometimes when driving, all of a sudden the car would give message saying something like "Reduced power" and it would go into limp mode. I picked car up and sure enough while driving an hour home I was on the 401 highway doing 120km and it just died and went into limp mode. It was extremely dangerous because it was rush hour and I had to cross 5 lanes of traffic with flashers on doing 30kms. Scared the crap out of me. He said he just disconnected battery then reconnected and it worked. This of course is temp fix. Do you think my problem could be this TCV you're working on here? Other than offering a limb and taking it to Volvo dealer I'd like to try finding problem and fixing myself. Sorry for the ramble...I'll blame it on being a Newfie. Cheers.
What is the ID of the vacuum lines. I'm going to replace and relocate the TCV as well as replace the vacuum lines with 3mm thick wall silicone instead of the stock rubber lines. Thanks in advance for your response.
Hi, How is it possible to display the "actual speed" on the trip computer? I can see it when you doing the adaptation. Mine displays average speed but not the actual speed.
Got a 2011 s40 y5 and I have a greddy ELECTRONIC boost controller that seems to fit on the electrical connection on the tvc. The connection will go to the aftermarket controller. Do you know if that would affect the wire that was originally I’ve gone back to the car???
There really isn't a whole lot you can do with preventative maintenance for a turbo. I would recommend running a magnetic drain plug as a safety, use a top quality oil, always let your engine idle for moment before shutting it off (with the engine running, the oil is flowing, and allows your turbo to spool down), and don't push the engine until it's up to operating temperature.
Hi, my c30 is leaking a little bit of oil which I'm told is coming from my turbo. I also sometimes hear a whistling noise when its idoling but doesn't happen everytime I drive. Any advice?
It's possible that your turbo is leaking out, this can be an internal or exterior leak. The exterior leak can be an oil line, if it's internal than a seal has failed on the shaft. The exterior leak can be viewed by looking at the rear of the engine, either from the top or bottom and a mirror would probably be helpful. An interior leak can only be seen by removing a boost pipe and you'll notice oil residue inside the piping or intercooler or if it's leaking on the exhaust side, you'll notice oil inside the exhaust at the turbo. As for the whistling, that can certainly be turbo related, so you may have a boost leak. Other issues which can sound like a turbo whistle is a faulty idler pulley or even a failed pvc diaphragm which I have a video for ruclips.net/video/1O4r1ftgJaQ/видео.html
I just replaced the TCV on my c30 with this unit, now my boost gauge is reading -20 lbs at idle instead of -10, and i am not getting accurate boost. my byass valve is no longer actuating. what did i do wrong?
@@tomamihai7695 after some digging i found that -20 vacuum at idle is actually normal. I replaced my PCV assembly and this fixed a vacuum leak i had prior. As for the turbo performance, it is pulling much better now. Took about 1 week of driving for the computer to figure out whats going on i guess. It feels a lot better, maybe not 100% still but id say 90 percent, hopefully will improve more over time
Ha...this makes it looks easy...it's not at all...extremely difficult to access and do the replacement...I installed this HD TCV and it doesn't work...going back to stock Pierburg TCV.
Not a dumb question at all, it's commonly asked. Volvos don't use a blow-off valve, they use a compressor bypass valve instead so it redirects the boost differently. People have successfully installed blow off valves, however I haven't.

Best time to do this is yours hasn’t failed it when your upgrading the charge pipes

Volvo v50 t5 awd, with jacks, take one hour to change, limited space, but pretty easy job. 57e new original part. (Heard its best)
how did you add the digital speed?
Best video I have seen and explaining very good

I have a question, what are the CBV's colors wire (Turbo control valve).? i cut de wire with connector and i didn't find it
Hey mate, i have the 05 AWD M66 S40 T5, is this method the same to get to the TCV as well or will the subframe have to be lowered to access this?
Should be the same, the C30 and S40 share the same platform (P1).
Hi! I could not find the part in the website.
Is it the same on a D5?
I just replaced the TCV on my c30 with this unit, now my boost gauge is reading -20 lbs at idle instead of -10, and i am not getting accurate boost. my byass valve is no longer actuating. what did i do wrong?
i have the same problem at my s40 did u fix it?
@@tomamihai7695 after some digging i found that -20 vacuum at idle is actually normal. I replaced my PCV assembly and this fixed a vacuum leak i had prior.

It feels a lot better, maybe not 100% still but id say 90 percent, hopefully will improve more over time
It is the correct number if read less than -20 somewhere is a problem, my car vacuum at idle is -22
Does the battery need to be disconnected before installing?
No need as there shouldn't be any power at the TCV when the key is off.
Hello. Where is the TCV on a Volvo with the 2.0d engine?
Unfortunately I'm not sure, we never had the diesel available in Canada. Best to ask on a Volvo forum/group.
Is this the turbo boost sensor?
Boost sensor us near the intercooler, also called map sensor
Ha...this makes it looks easy...it's not at all...extremely difficult to access and do the replacement...I installed this HD TCV and it doesn't work...going back to stock Pierburg TCV.
Can it be used for Volvo V50 1.6?
And where to buy?
Dumb question, where do I install the blow off valve?
Not a dumb question at all, it's commonly asked. Volvos don't use a blow-off valve, they use a compressor bypass valve instead so it redirects the boost differently. People have successfully installed blow off valves, however I haven't.
@@4DIYers very good to know, I would have broke something else. Thanks for the reply!
Could you provide the part number?
