Check to see if one of the plugs are saturated with oil due to a bad valve cover gasket

Check Engine Light see codes below


P0171 is LEAN and P0303 is misfire number 3 cyl. Its time to stop guessing and pay for a correct diagnosis. Find a shop that works on VW and has the tools to work on it. DO NOT put those Bosch Platinum Spark plugs in that Ottozone tries to sell everybody.

My 2001 VW Beetle is stalling. I had a tune up done and the mass air flow sensor and it is still happenning. The check engine light comes on and flashes then it stays on.


check engine light flashing means misfire and it staying on is probably because of your o2 sensor picking up all the unburnt fuel. check all the spark plugs again and make sure you didn't cross any wires. i'm pretty sure the wires were crossed or the spark plugs were fouled

What is the final word on which fuel to run in vw beetle turbo....i get conflicting information...my check engine also comes on and the code says misfire..help!


Use premium. If you use reg and hear knocking sounds, that is a problem.
Your misfire is most likely a bad spark plug. Make sure that you use OEM plugs only. Any other plug can ruin your ignition coil. Check the plug wires resistance with an OHM meter. Any out of specs need to be replaced.
It is possible the coil is damaged, but can be checked the same way as the plug wires.
Check for clean air filter.
If this doesn't solve the issue, then go through the fuel system. Change the fuel filter. Listen for constant ticking sound in fuel injectors. Use an injector cleaner in the next fuel up.
Good Luck!

2001 20 vw beetle engine managmemt light keeps comming on told it was misfire on no4 all new plugs light reset run for three days light back on HELP


Certainly the person telling you this had a scan tool but did not investigate thoroughly why it was misfiring and only suggested a bad plug in cyl #4. A bad plug is usually the case maybe from a mixed matched set of plugs. Having a distributor-less system some people miss to check the ignition coil pack. Technically you can't correct a problem by resetting it's warning indicator which some people think they have a red FIX button. In this case the engine management needed 3 start up cycles to verify if problem was fixed after erasing the DTC stored in the system, hence the 3 days. The ignition coil pack could be going bad or the individual ignition wire is. Is this an AEG engine code?

2004 Audi A4 misfire


it is always a good idea to stay with o.e.m parts and yes there is updated parts in the newer coils. and yes the M.A.F will also cause misfire faults but will not make check engine light flash or make car shake and shudder. also check you wire harness going to your coils make sure your ground wires are not cracked. That could be the main culprate. good luck hope this helps

Have fault code P0302 on 2001 VW Beetle. No it is Cylinder 2 misfire. What is likely cause, bad spark plug, wire, or Electronic ignition box?


this car has what is called coil over ignition which means no plug wires or cap so if it is missing swap coil from cyl 2 and any other cyl then clear code and rerun car till light comes back on then check code if it is still cyl 2 missfire then replace that plug if code changes to the cylinder that 2's coil was on then replace that coil <that car does have a recall for coils> if car is not missing and you have that code most likely isnt an ignition problem but will have a small vaccume leak so check the small hoses for leaks. very common for fuel preasure regulater vaccume hose to brake from age
