Luppy Jack Posted August 8, 2013 Report Share Posted August 8, 2013 Hi guys,My loop has been surging on idle, (ie revving up and down slightly) and randomly losing power whilst driving.Went to pick up my car today from my mechanic only to find it's too low to get in his garage Anyway I got the diagnostic sheet and figured i'd have a go myself- the code is:16492- manifold/barometric pressure sensor (G71)/(F96)P0108 - 35-00 - signal too high readiness:1000 0101Searching the code returns: Possible CausesWiring and/or connections faulty (Short to Plus)Leak in intake and/or exhaustG71 and/or F96 faultyControl Module faultyMy plan of action is too-Clean throttle bodyreplace plugs (haven't been done yet and at 52k)Check all pipes not losing airIf this doesn't solve the issue:Replace coilpack+ht leadsReplace manifold sensorDoes this plan sound sensible?anything missed?Many many thanks,Jack!

danoid Posted August 9, 2013 Report Share Posted August 9, 2013 (edited) Barometric is the MAP sensorhttp://wiki.ross-tech.com/wiki/index.php/16492/P0108If the signs show it's that doing the sparks/ht leads might just be wasted money. It's always good to change them though Edited August 9, 2013 by danoid Quote Link to comment Share on other sites More sharing options...
Luppy Jack Posted August 9, 2013 Author Report Share Posted August 9, 2013 remove and clean the EGR valve Saw a guide on how to do this recently and forgot about it- cheers buddy!Barometric is the MAP sensorhttp://wiki.ross-tech.com/wiki/index.php/16492/P0108If the signs show it's that doing the sparks/ht leads might just be wasted money. It's always good to change them thoughYeah I saw that although the experienced VW mechanic that diagnosed it said he'd only ever changed one MAP sensor in his career, and said its more probable the sensor is receiving the wrong information caused by another issue (such as a misfire or throttle body) causing it to show up, if that makes any sense! I'll remove the MAP sensor and clean it got quoted £40 for a new one from tps Quote Link to comment Share on other sites More sharing options...
danoid Posted August 9, 2013 Report Share Posted August 9, 2013 Ah, well tbh I dead hear that MAP's are soooo much better than MAF's and you can even use K&N oil filters with MAPs whereas MAF's you can't.How are you using TPS? it says trade only when I try and register Quote Link to comment Share on other sites More sharing options...
lupoluke Posted August 9, 2013 Report Share Posted August 9, 2013 Your on the right tracks, I would change the map sensor last they very rarely go wrong. Quote Link to comment Share on other sites More sharing options...

Not quite sure I undersstand what you mean about MAP/MAF? is there a difference? I thought the only MAP sensor was located to the rear left under the rocker cover?Your on the right tracks, I would change the map sensor last they very rarely go wrong.Cheers for confirming this for me mate Quote Link to comment Share on other sites More sharing options...
Luppy Jack Posted August 10, 2013 Author Report Share Posted August 10, 2013 (edited) Today I replace the plugs, cleaned the throttle body and inspected the MAP sensor(no obvious visible damage)The engine management light has now disappeared However, the EPC light is still on, this leads me to believe the MAP sensor and/or brake light switch need replacing.My rear lights work when the brake is pushed, could the brake switch still be showing as faulty even though it appears to be working ?Thanks again!
