Disconnect N422 (solenoid)located on the bulkhead on the passenger side RH drive vehicle) it is just beneath the water repellent cover beside the wiper arm, and see if if the fuse stays alive because fuse numbers 14 powers up V400 and N422.

Hi, the fuse blows even when both are disconnected. But the fuse only blows when I switch on the heater... ​@@stanhopeautorepaircentrewardak

Will V50 not give the same code?

Bonjour, je voulais savoir j'avais un voyant moteur allumé sur ma audi A3 2008 140ch qui m'indiquai la pompe a eau auditionel, du coup je l'ai remplacé par une neuve et ensuite je l'est retirer avec la valise mais le voyant moteur ce remet, du coup je sais pas le problème peut venir de quoi on ma dit peut-être le relais, ou le faisceau

First, check the fuse if the fuse is alive. If the fuse is blown after replacing it, then follow the steps below:
Disconnect N422 (solenoid)located on the bulkhead on the passenger side RH drive vehicle) it is just beneath the water repellent cover beside the wiper arm, and see if if the fuse stays alive because fuse numbers 14 powers up V400 and N422.

So in conclusion, you can try to replace fuse #14(in the engine bay) and if it keeps blowing, you have to replace the pump under the manifold, right?

This fuse powers up V400 Pump and N422 solenoid. It could be any of them, or the circuit may be short to ground before reaching the components.in my case scenario, it was V400 pump.
