Hello to all A2 owners!
Long story short - bought my mom Audi A2 one year ago and since then I have to look after this car much often than I would ever wanted. I like to get things done right and cure this car whatever "illness" it might have. There are several parts which I can't identify by online catalog so help would be appreciated!
It's Left Hand Drive 1.4i (AUA)
1. Water is pouring inside engine compartment (when raining or washing the car) and I have located source of this water leak, but can not fin'd part # that would cure this problem! It might be some kind of rubber grommet for this hole, but online parts diagram shows nothing... Can someone post photo of what you have there?
2. Upper coolant hose is leaking. I could try cure this with better clamp, but I want to change the hose so I would forget about his problem for some time. According to Audi catalog diagram there are at least few part numbers for upper hose. How can I know which one of them is the one I need for my AUA? 8Z0 121 101 P / 8Z0 121 107 L / 8Z0 121 101 K / 8Z0 121 101 Q
3. EGR - insufficient flow. Throttle body is cleaned, steel pipe going from EGR valve to throttle body is clean. Bought brand new Pierburg EGR valve, performed adaption via VAG-com and problem still persists! I am now thinking of removing aluminum flange between cylinder head and EGR to see if it's not restricting flow there... Any other ideas or suggestions?
4. Famous cylinder 1 and cylinder 2 misfires. New ignition coil, new spark plug wires, and spark plugs., got different used fuel injectors, new cam and crank position sensors, new coolant temperature sensor. Problem still persists! Most of the time check engine light comes up when car IDLE's. When it starts blinking, it's hard to drive the car. Sometimes engine light just lights and driving is fine.
This winter we had problem with frozen crankcase ventilation which led to oil all over the engine compartment and one of the camshafts stalling. We polished camshaft seat places from stuck aluminum and resurfaced cam seat journals. Well... car is driving and probably oil pressure suffers little from this damage, but car does drive. Now reading all the misfire problems people are having due to worn cam journals, I am thinking maybe I will have to find different cam and cam cover.
