Ill just run this thread, and see if anyone else is interested. these are my experiences and I am NOT an experienced tdi guy, nor am I a mechanic. Im just a guy that likes cars and likes to do his own work when possible.
I purchased a used 2012 a3 with 68k mi. It is post-emissions fix and warranty is good until December 2023 or 116k mi (I mean hot damn- not bad for a used car) I bought the car from a wholesaler who purchases at auction, I have been watching for a few months and this seemed the cheapest way to go, paid $7800 for the car. no owners manual, no maps disc, no floor mats, no spare tire, pilfered before buyback im sure, but hey the price seemed right.
Given that the car has been sitting for a few years I figured I would give her a fluid refresher, so changed oil/filter and transmission fluid/filter.
anything else anyone suggests? air filter looks good- previous owner put k&n so ill leave it be. fuel filter?
per carfax- fuel filter/pump/and tank replaced at 25k mi.
- spark plugs replaced at 55k
after oil/dsg service the car threw some check engine codes (within 50 miles)
P2002 - particulate trap efficiency below threshold bank 1
P0401 - exhaust gas recirc flow insufficient detected
8194 - no DTC definition found (something dpf related)
1025 - air bag malfunction indicator lamp ("stored mil")- not an issue?
2214 - no DTC definition found (no idea- but "stored")
1325 - no DTC definition found ("stored")
looked around on tdiforums- evidently the P2002 and P0401 are a known recurrent issue with these cars- not sure about the others any insights?
I contacted the local dealership and he said any causes of those 2 codes should be covered under that sweet warranty so Ill be scheduling with them asap. Is there anything in particular to ask the dealership for or about? my concern is that theyll hit the reset and tell me im good to go?
I am learning about this regen process, any chance these codes clear after a few regens? ive only put about 300 miles on it since i bought it...
Thanks in advance for your time!
