Question about 2005 Audi S4
I had a tune up on my 2005 Audi S4 Cabriolet. The ignition coils were not replaced as part of the original tune up, but the valve covers were removed and new gaskets were installed. The car has 50,000 miles. When I drove away, many of the cyliners stopped working (apparently 4 or 5 of the ignition coils stopped working) after 5 blocks.
A problem occured because the mechanic could not spend time to troubleshoot that day and sent me on my way home. On the way home (traveling for 10 miles at 50 mph) on a few cylinders, a fire started below the passenger compartment. I was rescued by farmer with fire extinguisher. The mechanic said raw fuel was sent out the exhaust and catylitic converter must have been so hot insulation below passenger compartment caught fire.
It seems odd that this happened after the work I had done on it. Could mechanic have caused the ignition coils to be effected. It required 8 new coils and 2 O2 sensors, a new shifter which also melted.
Any thoughts you may have to explain these events would help.
If you replaced the coils the spark plugs should also be change. The plugs are more than likely bad.
