I guess I'd ignore this if I hadn't noticed today after getting the "check engine" light come on yesterday. Trouble code 32 55 which I understand thanks to an answer I had earlier, but now the rev counter as well? Is my Jeep going senile on me?
SOURCE: Trouble code 54 on a 1995 Jeep Grand Cherokee
Carb'ed Engines:
Code 54 - Mixture Control (MC) solenoid is shorted or the ECM is faulty.
Fuel Injected Engines:
Code 54 - Camshaft (or distributor sync.) reference circuit - No camshaft position sensor signal detected during engine rotation.
Hope this helps

Take it to any Autozone or Advance Auto. They will check it for free! Probably other similar stores will do the same!

Don't know much about VW but if it's fine, and it doesn't happen again I wouldn't worry about it. If it does try resetting the ECU by removing the battery terminals and touching the positive lead(red wire) to the negative battery post. It might spark a little, this is just the capacitors discharging, resetting your ECU and starting over. It's like restarting your personal computer

I appreciate that the trouble code and the check engine light should have nothing to do with the RPM guage, but it seems a little suspicious to me that both problems have come within 24 hours. The Cherokee is a 2.5 TD limited 1994.
The other thing worth mentioning I suppose is that otherwise it is running very sweetly indeed: starts first time every time; stays at very steady temperature; oil pressure seems very steady etc etc.
Any advice would be helpful although I appreciate that my next step is to buy a Haynes manual and try to address the first error code 32.
Okay thanks emissionwiz... I guess I'll get on ebay and chase down that Haynes manual
Okay thanks for that advice emissionwiz - I shall see what I can find online. Thanks very much indeed for the advice
buy a factory manual, the Haynes books are not up to the task of emission repair diagnostics
DTC - 32 EGR system failure
Year And Enine Size? ANd REV Counter -- RPM Gauge or Tachometer-Tach Head REEK Havic on Some Havic on some Jeeps een a while I maybe could SOLVE with A Liittle more Detail
that is not a code.The check engine light has nothing to do with the tachometer operation unless there is a miss then it may jump around from the RFsignal generated by the misfire.
