Asked by Jul 19, 2017 at 02:39 PM about the 2010 Audi A4 2.0T Premium Plus Sedan FWD

Question type: Maintenance & Repair

Car had little bit of power loss before. Would take a little bit longer to start. Couple days later tried to start and it wouldn't even attempt. All lights and radio will turn on but no motor. A mechanic said timing belt slipped and top end needs to be rebuilt, but that doesn't make much sense to me considering everything leading up to it not starting. Any ideas??

2010 Audi A4 premium plus Up to date oil changes, tune up about a year ago. Car started to lose power, not a lot. Would take a little bit longer for the engine to turn over and actually start. Parked it for a couple days, tried to start it to take it to a shop and engine wouldn't start. Just makes one click noise and everything else in the interior turn on as normal. Then EPC light was illuminated.

Also, AC would be cold and turn a coolish warm tempature and then back to cold as car was driving

Since the EPC is used on multiple other systems on the vehicle, it is likely that other warning lights will be illuminated on the dash as well. Typically, the stability control and cruise control will be disabled and their respective lights will be illuminated as well. The check engine light may also come on to show that the engine itself isn’t operating at normal efficiency. To try and protect the engine, the computer can limit the vehicle’s throttle and the car may feel sluggish as a result. You will need to get the car scanned for trouble codes that can be used to identify the problem. Once repairs have been done and the codes cleared, everything should return to normal.

But that's the thing, no other lights were on but the EPC light. Do the symptoms seem like it could need the top end being rebuilt?

EPC light means it`s protecting something and throttle will very. Please understand if the top was redone, something went wrong. Or the computer was never reset for new top. Get an expert on your car a.s.a.p. It will break down. Sorry to say. Let me know.

This might help. Epc light was on with my Audi for long time. Fighting speed and all other lights keep coming on. My battery went out and I changed to a new one and everything went away. I don't know if new battery did the job but so far epc light, engine light are off two weeks and still off.

1 click when turn the key makes it sound like the battery is dead or low voltage maybe need new battery.... With epc light the most common problem when this light is on is due to electical issues...could be coil pack pin connector wires are broken inside and are stuck together or connector to crank sensor or camshaft sensor...just pull the rubber cover down on those connector and you should be able to see the wires...good luck

My 2009 was idling rough at stop lights, EPC light and engine light on also ESP light and brake light was on. Took it to Audi they replaced the oil control valve and replaced battery.
