seanl82 23 Posted March 22, 2015 Oil temp is good. Can get up to 120 if really giving it some so nothing to worry about. Only way to tell if it's been chipped is to remove the ECU, open it up and check the eprom. Quote Share this post Link to post Share on other sites

Subs???) Am missing a battery clamp :( What is this?!!! Lambda sensor socket has 2 cut wires??? Lambda plug also 2 cut wires? This BLACK cable what is??? Is my lambda working then? Paid £100 and had it replaced already?!!! Quote Share this post Link to post Share on other sites
seanl82 23 Posted March 22, 2015 Yep that's lambda. I'd be pretty unhappy with the garage that did the work if they apparently changed it!!!!! Quote Share this post Link to post Share on other sites
Sean_Jaymo 0 Posted March 22, 2015 A loose battery terminal will cause stalling. Lambda wiring will also cause all sorts of running issues. Quote Share this post Link to post Share on other sites
delfinis38 1 Posted March 22, 2015 when I had my airco put in years ago some oink never put my battery clamp back, it had a big penny washer holding it in for years.... eBay's your friend for battery clamp.... or if your cleaver make your own. Quote Share this post Link to post Share on other sites
Wayne2015 10 Posted March 22, 2015 Havent brought my scanner along :( Will test lambda next time when Sanky is free to dis/connect the lambda plug... Quote Share this post Link to post Share on other sites
seanl82 23 Posted March 22, 2015 I'd do it now Wayne. It's a possible cause of your issues and its pointless chasing your arse whilst there's something obviously wrong. Will only take 2 mins to reconnect and insulate temporarily to at least find out if it's the cause. Quote Share this post Link to post Share on other sites

Even Sanky not confident reconnecting ... Quote Share this post Link to post Share on other sites

Wayne2015 10 Posted March 22, 2015 Google brought up this http://www.lambdasensor.com/main/mcolours1.htm Cheers Dox! But since other 2 cables cut - we dont know how to connect as removed from plug and socket.. That is its been cut from source i think ... Quote Share this post Link to post Share on other sites
Dox 23 Posted March 22, 2015 Cut the plugs off and hard wire them? or get someone to cut a section of loom off for you, either way its connecting 4 wire together. Quote Share this post Link to post Share on other sites
Wayne2015 10 Posted March 22, 2015 Cut the plugs off and hard wire them? or get someone to cut a section of loom off for you, either way its connecting 4 wire together. So we absolutely sure we need 4 wires connected for Lambda? Ok Plan: 1. Just drove C home - not stalled yet! :thumb right: :shades: - so leave as is for now 2. When stock airbox arrives - will fit that 3. If still no stall - i prefer to leave the lambda sensor alone. - what will be downside not reconnect all 4 wires? Again many many thanks to another forum member, Sanky For sacrificing 1/2 his lovely sunny warm Sunday to look after my car :) We did: 1. Clean ISV (again) 2. Clean throttle body Now will see how it goes ... Quote Share this post Link to post Share on other sites
Dox 23 Posted March 22, 2015 If I had to guess I'd say the heater in the lambda was shorting blowing a fuse so they cut the wires to it? The heater is used to make the lambda read faster from a cold start, without it the exhaust gasses will have to heat the lambda to its working temp. As you've fitted a new lambda there shouldn't ba a problem any longer, VW fitted 4 wires because it needs 4 wires for optimum performance Quote Share this post Link to post Share on other sites
seanl82 23 Posted March 22, 2015 Depending on what the wires are for, it could be affecting fuelling and would have a big affect on emissions. You can see the insulation where they've been cut in the past, so they're obviously supposed to be there. I wouldn't leave it tbh mate. I don't have my bentley at home so can't check, but if someone checks their wiring diagrams at the back of it, that'll tell you where its connected and what is likely to be affected.

Wonder what the other side is like :eek: U think i need to check all the lambda connectors Quote Share this post Link to post Share on other sites

sankysvr6 0 Posted March 22, 2015 Let me just clarify about the lambda sensor, 2 wires are connected with the car loom and 2 wires are connected with butt connectors. The reason for this is I think is, the connections have broken on the car plug . The Black wire that's not connected is on the car loom, but not sure where it's meant to go. As the plug from the lamda has all its 4 wires connected, it's hopefully wired properly. Will have look at the wiring diagram and see what's what.

seanl82 23 Posted March 22, 2015 Ah so all 4 are connected, just only 2 via the plug. Fair enough then. Think it'll still be worth getting a pigtail from a car being broken and reinstate it though. Quote Share this post Link to post Share on other sites
Chuggs1 10 Posted March 22, 2015 Just looked in my Bentley and reading wiring diagrams is like reading ancient Egyptian without the Rosetta stone! Quote Share this post Link to post Share on other sites
seanl82 23 Posted March 22, 2015 In fact, I may even have a lambda socket I could post up to you Wayne. Let me have a look among my spare wiring harnesses and I'll get back to you. I'll check after work tomorrow, at the moment, I'm watching Bristol City in the JPT Final!!!!! COYR!!! Quote Share this post Link to post Share on other sites
