Hey All,
So I've recently done some major repairs on my 2005 TDI Wagon (5-speed) including replacing the intercooler, lift pump, fuel filter and airbags after a collision in the front right corner.
When I first took it out for a test drive I noticed stuttering at low throttle, especially in second gear. After a bit of driving through the city this subsided and I just chalked it up to some air in the fuel lines (although it did feel like I still had low power in 2nd gear).
So I park it overnight and the next day I get on the freeway and around 40 MPH my check engine light comes on. I didn't have a choice and I wound up driving another 10ish miles over which I notice I'm getting significantly reduced power. Can barely hit 65 MPH and very noticeably less power in second gear (but no stuttering).
So I ran a scan with VCDS lite on the engine module and got 4 errors including mass flow sensor (improbable signal) but foolishly forgot to save the output (lesson learned). I cleared the errors which turned off the check engine light and the stuttering immediately returned. I drove around a bit including getting back up to speed but couldn't get the engine light back on. The stuttering is back but only at low throttle and power loss is very noticeable.
I'm hoping that someone has an idea about what is causing this based on my account. I will update with the VCDS scan info as soon as I can get the engine light back on.
Thanks in advance for any ideas.
