Hello everyone having similar sort of issues , any help would be much appreciated ,, trouble with my 04 plate a3 2.0 tdi , the car loses power in first and second makes a lot of noise but doesn't really go anywhere but if ease completely off and back on again the turbo kicks in properly it also won't go over 4000 rpm unless I go off and on the throttle any help would be greatly appreciated also I took the vacuum resivour pipe off whilst checking a few things and it cured it until I was cruising down the motorway and it just lost all power so I stopped and put vacuum resivour pipe back on and after about 15 mins the vacuum must have built back up again because it was back to just being useless in 1st and 2nd gear ..???????? Help !!!! I'm lost
Hi, some jags are fitted with dual alarms, is your alarm sounding through the main horns and flashing the lights? or are you getting a loud beeping noise. If its beeping then its the Passive alarm system. you need to say what one it is, I am asumming its the original alrm and not aftermarket.
It's most likely the turbocharger. We used to have an Audi with a turbo and it had a bit of a whine when accellerating. A slight siren type of noise is normal for it, but, if it's real loud then it should be checked.
may not be the answer your looking for but most prestige cars have a seat alarm that will activate if you have something sitting on passenger seat.handbag etc. computer thinks someone is sitting there and they are not wearing a seatbelt
Your motor probably runs in "failsafe" mode (won't go past 3000rpm in highest gear), but in that case the ECU warning light should also come on (which might also be broken ofcourse).
Try releasing and reconnecting the battery (-connectors), which should "reset" any fault-codes in the ECU and see if the TDI power is back. Please note that the "cause" of the ECU faultcodes will probably put the motor back in "failsafe" mode within minutes ! But at least you've verified that your motor runs in "failsafe" mode due to serious faultcodes in the ECU.
You should have a dealer/expert read the ECU faultcodes using VAGCOM to determine the cause. A dealer will charge something like 50~60$ for it.
Since it's a 1.9TDI my best guess is that's it a broken N75 turbo-valve (common TDI issue, replacing the part yourself will cost less than $30 and 15 minutes). When the dealer suggests a complete replacement of the Turbo-unit (quite expensive), please have a TDI-expert do an 2nd opinion ...
