My Passat 2002 T 1.8 Petrol won't start after battery change

Hi, I replaced the old flat battery for my VW Passat Turbo 2002 and now it won't start. However it cranks well and seems like wanting to start but no spark for the engine. Probably some redoing of electronics etc is needed for the car to accept the new battery? I did some preliminary things and a mechanic also came to have a view but his gadget did not accept the codes to do the adaptation. Do you have a fix for me? What I tried already: 1. Insert key to driver door, 30 sec press right, 30 sec press left, press the remote lock buttton for 30 secs. It did open and close the windows, but no luck in starting. 2. remove + terminal of battery, wait for 10 minutes, attach +terminal again and try. I could see the clock etc starting fresh but no luck with starting. Regards

SOURCE: electronic immobilizer

most likely cause is the gauge cluster, this will have to be tested and service by your local dealership because the dash cluster and keys have to be coded. I have seen the immobilizer loose it's coding for apearantly no reason. therefore have them recode cluster and see if problem goes away, if it doesn't the gauge cluster will have to be replaced.

It sounds like your Power Door Lock Relay is working intermintently. Bypass the relay and test the Power Door Locks with a jumper wire direct from the battery, if they work with no hesitation then it is a bad relay.

Where is the turbine speed sensor located on a 2002 vw Passat 2.8 l 2 wheel drive


The 2.8 is not a turbo charged engine, so would not have a turbine speed sensor. The 1.8 or 2.0 were turbo charged.

My 2006 2.0 tdi passat keeps going in limp mode and saying emissions workshop. Can anybody help


hi mate, my 55 plate passat did the same before major problems happened. first turbo went then the oil pressure light came on and the car went into limp mode. before its too late for you and a costly bill can you do the following.
check if your car has a recall for the injector problems which vw are replacing under warenty.
second thing the guy who repaired my turbo told me that these cares have a major fault which caused the turbo to go. the fault is the oil pump failure you must adress this issue as you can get a lot of info on the discussion forms.
my car started with the same problem as you have described the pd engines have a design fault with the oil pump and shaft. this is common causing your turbo to go then the car will start showing oil pressure low please stop engine. educate your self via the forms and act quickly befor you end up with massive bills.
i hope this has helped. trust me vw know about this design fault.you need to change your chain driven oil pump to the new gear driven system which vw have modified. all vag cars have the same problems be it audi skoda vw . my car had the same problem as you have said .started off with emissions then turbo failed thats when i started to investigate this problem . the pd engines was designed by some rookie at vw.

Hi In my VW Passat 2002 model with 118K I got oil pressure indicator and stop sign in dashboard. and got off. what I have to do now?


Oh no sorry to hear that. You did the right thing by stopping. If you have the 1.8 turbo engine this happens too often. The oil pressure sending unit could be the problem, but most likely it is the oil pump. This engine has sludge buildup problem & VW is aware of it, so there is hope. VW issued this update awhile back....

Passat owners. 1998 through 2004: VW has just made a warranty extension covering certain oil sludge repairs on these models. It is now covered for 8 years unlimited mileage and will reimburse for repairs made because of this problem. See your local dealer or contact VOA for more information.

Good luck, i hope this helps.

Vw passat 1.8t battery problem?


Hi

Either your battery has just given up the ghost,........ Is it the original, and now 10 yrs old ?
Or your Alternator is not charging enough, to replenish what is used.

Have battery tested first, if OK, then the alternator belt tension, and alternator for correct output charging rate.

If all these shows no faults, your starter is then suspect.

Good Luck !

A FixYa would be nice thanks !....John.

The flashing is telling you that the engine is mis-firing, the dealer will run a test to determine the cylinder that is mis-firing, chances are it is something simple
