Hi, The EGR valve itself is on a set of flexible pipework - usually stainless steel - which runs between the inlet manifold and the exhaust manifold. The EGR actuator valve is pneumatically / vacuum operated by a solenoid valve, controlled by the ECU ( aka the brane). It's not usual for the EGR valve itself to fail, more likely the solenoid valve or its electrical connector getting dirty. If you google for VAG TDI N75 valve you should get all the info you could possibly ever need :-)

Hope this helps, D.

Ok very carefully pull off the mirrior blade. The mirrior blade is clipped but EXTEMELY fragile and will break if forced. From there remove the 2 heated blade wires. The cover is also clipped as you will notice after that is removed. You have to pry with a plastic tip between the cover and hosing near the body of the car while pulling the clips in the housing you see to lift the cover straight up. Once this is done you'll need a t-10 torx screwdriver to remove the lower portion. These screws are when you're looking straight down. With this assembly off you can access the 2 other little screws holding the flasher to the bottom cover. Remove the wires and the little clip and there you go. Installation is reverse.

I just replied to someone having the same problem with a Honda and saw one of the sponsors pop up in the Ads by Google box to the right that may help. I think with Hondas you have to go to the dealership where the car/radio was originally purchased and give them some numbers from the radio. The sponsor may charge to get the number for you but it may be worth a few bucks if that is the only solution. I didn't catch the web address or name - sorry.

Your EGR Valve is clogged and has to be changed. I have tried removing, cleaning and replacing it, this only lasts from one hour to one week.

The fault code 'P3103 V157 - Intake Manifold Flap' comes up on the diagnostics, and if you look in your fuse box (next to the battery) you will see a blown 10amp fuse. This is a sure sign that your EGR (or Intake Manifold Flap) is stuck.

This unit costs about £235 - £250.
Good luck mate

Please Help! I brought a vw golf 2.0 petrol gti, 2000 plate. when I turn ignition on it says "service now" however today whilst driving on two separate occasions, the batter light came on, power died on...


what are the diagnostic codes? if they are manufacturer codes they should be 5 digits, if they are generated using a non manufacturer scan tool they will be 5 digits beginning with a letter, in your case most likely P for powertrain then four numbers ex. p0121, you may also have U codes or B codes which are basically body and communication codes. Scan the codes, write em down, clear them again, and see which ones come back. The better scan tool the more info you can extract from the vehicle. Keep an eye on the check engine light, immobiliser/security lights etc. Could be a key/programming/relearn issue. Im here if you need me.

Yellow warning light coming on that looks like exhaust pipe


You need a code scanner hooked up to it to find out why that light is on. If you have an autozone near you,go there they will hook one up for you. Takes about 30 to 40 seconds. If not call around.
