Title: Fault codes ?
Post by: jockgti on 01 March 2012, 21:18
couldn't find the fault in my book or on rosstech but was in garage section on here

17968 P1560 Maximum Engine Speed Exceeded ??? i didn't even get over 30mph before it came up stop coolant warning opened bonnet and it was boiling the water,was driving maybe 15mins at most,car felt weird as it wasn't heating up inside,then all of a sudden the warning came on.

17840 Possible Causes
Secondary Air Injection Solenoid Valve (N112) faulty
Secondary Air Pump Relay (J299) faulty
Possible Solutions
Check Secondary Air Injection Solenoid Valve (N112)
Check Secondary Air Pump Relay (J299)

i've removed my 112 valve and replaced with resistor could resistor be dead or is it more likely to be relay? and where is it? would any of these cause the water to boil? and car overheat? cheers

See if water is being circulated back into the tank with the engine running / Remove the top hose and it should have water coming through  :smiley:

You need to remove the cam belt so if its old will be worth replacing the belt and tensioners too.

Clear the codes and see if any return as they may be old faults that have been fixed  :smiley:

water pump and belt changed a few month after i got the car a year ago,although everything that guy did to my car so far has broke or been replaced and i'm not sure if he even changed to be honest,i've started using a different garage now and hes really good but a bit more expensive than others but really knows his stuff and is well in to tuning cars,he wants to get into remapping vw's as he already does a lot of jap crap,i'll phone him in morning see if he can hook it up to proper vagcom

The impeller can spin on the shaft so as you say it will let some water past, Rev it up a bit  :smiley:

ecp just replied to my question saying the more expensive oem pump has plastic impellor and cheaper aftermarket one has metal which seems weird then if metal is better

Just get  a genuine one from VW with plastic impeller and replace at every cambelt change.

 I heard the metal ones can seize and throw the belt, that's why VW make them from plastic so when it fails it just spins on the shaft.

Not sure how true that is though  :undecided:
