Just scanned the golf and it showed up 8 errors, one begin no signal from lambda Need a new battery, could some of these errors be due to low battery? literally had the ignition on for 1 minute and went to start and not even enough to crank the car 8 Faults Found: 00668 - Supply Voltage Terminal 30 07-10 - Signal too Low - Intermittent 00524 - Knock Sensor 1 (G61) 29-00 - Short to Ground 00518 - Throttle Position Sensor (G69) 30-00 - Open or Short to Plus 00527 - Intake Manifold Temperature Sensor (G72) 29-00 - Short to Ground 00516 - Closed Throttle (Idle) Position Switch (F60) 30-10 - Open or Short to Plus - Intermittent 00525 - Oxygen (Lambda) Sensor (G39) 03-00 - No Signal 00635 - Oxygen (Lambda) Sensor Heating; Before CAT 31-00 - Open or Short to Ground 00522 - Engine Coolant Temperature Sensor (G62) 27-10 - Implausible Signal - Intermittent
Going to get new battery and wipe faults, someone mentioned buying a diesel battery.. is it worth it?
Bosch Silver is what you want (the one listed for the VR6, not the diesel). Best 90 you`ll ever spend. Lifetime warranty too.
so started car up (run vagcom) didnt keep just ignition on due to dying battery I clear all faults then it autoscans again, the car kinda shot up to 2k rev for about 2 secs (**** myself) haha, anyway only 2 faults showed up from previous list 2 Faults Found: 00524 - Knock Sensor 1 (G61) 29-00 - Short to Ground 00527 - Intake Manifold Temperature Sensor (G72) 29-00 - Short to Ground Readiness: N/A
i would suggest some background info on the car/engine setup in question would help a lot save's people trying to search of guess those details. as for the faults i would say a new battery and checking all your earth points and cleaning them up for a start further more i'd try swapping the mentioned faulty sensors with some known working ones if you can. find out if you have the same faults then
Sorry it's a vr6 with decat and full stainless powerflow (decat explains the lambda sensor not giving signal) Is the manifold sensor hard to change, been told the knock sensor needs to be tightened using a torq wrench
nearly all bolts from reading on etka and elsawin need to be tightened with a torque wrench but i doubt use one and my cars are fine (admittedly i could do with one for somethings)
Yes, all bolts need torquing to a specific tightness, and yes, most of the time you can get away with without using a torque wrench, but a knock sensor definitely has to be the correct torque for it to function correctly...
Update: found out that the knock must have had some bad connections as the person has by passed going into the plug (still operates as normal) Thinking these 'ground' issues are due to a bad battery, nearly died this morning.. could hardly idle.. had to give it a nice rev and hold it (no complaints from me)
