Questions and Answers

Volkswagen Jetta Hard Hot Restart

Q. I drive a 1996 Volkswagen Jetta 4 cylinder, manual transmission with about 135,000 miles. Lately, I've been experiencing trouble starting it. Problems began during short trips. I would run an errand only to have to try five or six times before the car would start before going to my next stop. Now on most occasions either it won't start at all or it will start only after several attempts.

Also, on some occasions the engine has idled up fairly high when I'm at a standstill. The battery is fairly new, two months old. I'm wondering if it's the starter. When I turn the ignition the car sounds like it's turning over, but it's like it never catches. Any help or information would be appreciated.

Thanks,
Marwin

A. If the engine is cranking, then it's not the starter. You didn't say if it was a gas or diesel engine, so I'm going to assume it's a gas engine.

If it's only hard to start when it's warm, I would have to suspect the Engine Coolant Temperature (ECT) Sensor. Volkswagen does not give specific measurements for the ECT and it has to be tested with a scan tool. The temperature should be within one or two degrees of the coolant temperature as measured with a thermometer.

Of course you should check the most common causes as well. Vacuum lines and electrical connectors for integrity, EGR valve etc. An engine with worn or old ignition parts and filters will also be hard to start when warm.
