struggling to start from cold
Hi folks, I have an issue with starting my 1.8T from cold , it takes on average 3 attempts to catch it to get going. ( starts first time when warm ). I looked on here last week and did read about cam sensor, so I replaced this last week before attempting to start and it fired first time so thought problem was solved .But next day it was back to the previous issue and again it will fire first time when warm and is only an issue when cold. I was reading about the orange clip issue although to my knowledge it has not been fitted ,I did purchase one a year or two back so if needed had already got one ready, probably barking up the wrong tree. The battery is fully charged and holds the charge as tested with draper battery analyser and reads all good so if some one has an idea it would be much appreciated, and point me in the right direction , cheers Paul

When you say "catch it" do you mean that the engine splutters as if it's firing on only one or two cylinders? If so I doubt it's the camshaft sensor. When mine suffered a poor connection recently there was absolutely no sign of life from the engine at all. I wouldn't put too much emphasis on the engine starting normally when warm. Cold starts require perfect engine tune so if there's any defect, however small, that's when it will make itself known. As you have the orange clip, why not lift the back seat and see if the filter canister can be tightened. It would be unwise to discount it. Simon

I had similar problems for a good while, particularly if the car had been standing for a couple of days or more.
Turned out to be a blocked in tank fuel filter. An unusual problem for our cars but not unheard of. |

struggling to start from cold
Hi Simon , I always turn the ignition on so you hear everything connect and all lights that should be on are on before attempting to start engine ( do this on modern cars as well as couple of classics I have ). Yes the engine does splutter as it attempts to fire up as if not running on all cylinders and like I say it will fire up on third attempt but it is still struggling, almost like when some of us remember manual chokes and you had flooded it. I run it with the digital temp display on dash and don`t drive off until temp is up to 33 degrees, so I don`t hurry the old girl. Yes I will check the filter canister as a possibility ( what joy now the weather has changed ) but as it`s colder everything is working harder to get that initial start so things are going to occur that probably wouldn`t had done in the milder weather. Thanks for that Simon, and thanks to mbonwick a blocked in tank fuel filter has been noted as a possibility. These are such lovely older cars I can`t imagine not driving it .

Thanks for coming back to us Paul. If you haven't done so already, check the sparking plugs for condition and gap.

On my CDTi similar symptoms were the forerunner of an injector failure. I would think it worthwhile to check those and the coil packs. Last edited by polinsteve; 26th November 2021 at 12:16.. |

As Simon says i would look at the spark plugs and consider re-gapping down to .7mm - the cold weather maybe causing the plug to struggle at a 1mm gap.

Gap the plugs to .75mm, possibly fit a new oxygen sensor as well if you haven't already
