the audi a4 is not part

[Zac]

hello all,I have a problem with this audi a4 1.9 tdi, a friend of mine, the machine was stopped for about a month and the battery was not able to start, reloaded,done the battery test all ok, refit in the car,provo is a part, turn off pass about 10 minutes and then try to turn it on and leave the radiator fans and the AC and the engine does not start ir?..... in the pi? known that the battery goes down? immediately in the space of 2/3 minutes to start tests.reloading the battery back in,reassemble turn on the ignition and I hear the low pressure pump in the tank turns as if it were under stress,I remove the entire pump,clean up around the provo bench, and it's good.... control the current that reaches the pump ok 12,4 v reassemble everything, I try and the car is in motion I do a tour, everything ok .then I turn off and try again to put in motion, and again leave the fans and the machine will not....... can be a problem of the ecu ??

the battery goes down it could be the was a bit poor....error in the ecu? recognize the key?

[marcogti]

that a4 are we talking about ? edc15 or edc16 ? the fans start even if you have the ac unplugged ? usually on edc15 the ventolo leave the programming mode .

[Zac]

between half an hour I got the diagnosis and I see.... I don't know that the ecu mounts, and the 130 bhp 2003

[Zac]

the battery and the good I have done recharge and test with a tool of tecnotest that so far has not ever wrong, I charge the battery 92% performance and start-up of 88% ,then find the battery

[Alfiuccio]

so we're talking about edc15 however, I do not think that it is the battery....maybe some of dtc, we will give you the straight away....

check the relay in the main, and in the case sotituiscilo

[Zac]

that's weird , I've double-checked the current that arrives at the pump BP voltage, and 12.3 v but if I check with the pilot light can not even turn it on !!

check the relay in the main, and in the case sotituiscilo

quoto perfectly wrapped in it is a rel? signed 109 or 119 I can't remember well under the dashboard on the driver's side, you just open it and redo the contacts

[Zac]

The diagnosis made with delphi,there are too many errors I have counted thirty!! relays, fans, ac ,positive to ground, short circuit,fuel pump,low voltage, etc, etc. under the dashboard on the relay I have checked all-to-one !!

[Zac]

raga not imagine.... I connected everything seemed to be a detective hahahahha my friend had parked the car right under a tree,in fact as soon as we went there were a lot of leaves above the car..... and many have gone to clog the drains to drain off the water that are under the hood in the battery compartment, etc, etc, when we arrived we water there was more but the leaves!!! I removed the cover where inside there and the control unit, and underneath are the relays that are in stock!!!!!! everything flooded....

[marcogti]

remember to clean out the hole you drain that is located under the battery itself.
and best wishes

[Zac]

Cleaned out all of the small drainage,all the relays one jo had to replace was too bad...cleared all the errors, all ok. fortunately, the unit has not had damage

check fuse # 10 + plug fans, if missed, are the fans in short,also check the throttle body, the last beach engine control unit and gone!!
