Service Bulletin Codes
 

I recently bought a '90 C4 911 and today found out that two service bulletins codes were never done: Codes WM03 and WM04, they couldn't as yet tell me what those codes mean, anyone know ? The carbs don't have that air vent (yet) and the heater/AC died at the same time, were both of them service bulletins ?

Thanks

I think you need to re-check the codes. You can subscribe to "www.alldata.com" and get access to all TSBs for your car, as well as a lot of other information....but it's about $20 for a 1 year subscription. I have a '91 C4 coupe and tried to find something that would reference the numbers that you posted, and there was nothing to be found (I think you have the wrong numbers).

Keep in mind that a TSB is NOT a recall, but anything from a recommendation to (in some cases) a procedure to make life easier for a mechanic.

Good Luck,
