Hi can anyone help my car is hard to start its a 1.9 tdi I've done the glow plugs still herd to start help plz
Could still have logged a code could be worth getting it plugged into Vagcom or similar. I would check the glow controller is working with a multimeter first.
does it smoke while trying to start,if not could be diesel running back and thus air in system when first starting]
seen this on a 2ltr PDI enigine in a 2006 A3 and it turned out to be the starter motor the part is roughly 150-200 depending on the place you buy it not the easiest job to do as space is tight in those bays but it is possible with a few scrapped knuckles
Battery? start of the cold weather is seeing lots of cars with struggling start ups on cold mornings.
I had difficult/not able to start with mine recently. Got a jump start to get running. While applying 3000rpm get a mate to put a voltmeter on the battery. If it won't read 13-14 volts the battery isn't getting recharged, your alternators gone. I was able to pick up a second hand on eBay for 40! (Check part nos carefully) and local garage electrician fitted it for 60. He took a tiny bit of persuasion simply that he wouldn't be liable if my second hand part didn't work and/or didn't solve it. Of course if the voltmeter shows a good voltage the battery is likely had it. Just noticing the advice given might be too late to be of help to the op. I'll leave it here, you never know someone else might find it in their hour of need.
Dependant on the model the injectors will not introduce fuel until the cranking speed reaches a set speed, more common startermotor fault is cold start perfect but you have to turn it over for a while before it'll start from hot
