Hey,

about a couple months ago i had my car taken to the shop where i was told that my car was pretty much done for...
Here was the diagnostic


I took a couple of pictures today and here are some pics to correspond to some of the problems.









They also added my car has gone through coolant migration.







as you can see i made the ill mistake of putting another coolant besides the g12 [:'(]


Not sure how to go about correcting this problem. I was thinking about replacing the entire wiring harness.

This will be my first time doing any type of car repair, im a complete novice but I'm ready to have some fun!

I would greatly appreciate any help. thanks!!

 

soooo.....what kind of car do you have?

I can only see a 1.8L motor....

year?

transmission?

drivetrain?

well, from the list of crap above...looks like a solid week of work and about $500 in parts and fluids.....

I would say that you need to get your car into service position and just do one thing at a time.....

hmmmm..... audidiy.com is going to be your friend.....

just make a parts-list and order it all at the same time.....

where are you located?.....there may be multiple people on the forum who may live close to you, with a nice set of tools who are willing to work for beer

you definately have a job ahead of you.....

you don't need a new wiring harness, you just need to order the electrical connections that have fallen apart....

besides that, I would attack the motor first....focus on all of your gaskets and such, and get the car running well, before you worry about steering/suspension/brakes/wheel bearings and aesthetics.....

alright....well....get working!

only use audi/vw specific fluids

gl!

 

you should probly cut your fingernails too lmao im just messing i know I dont help

 

LOL i knew someone was going to comment on the fingernail. the boogers gotta come out somehow lol...

But its a 1998 audi a4 1.8t tiptronic FRONT track and it has about 89,000 miles on it

 

Well i thought about splicing the wire but i need new wires to go from the ecu to the sensor, and im not sure how to connect the new wires it to the connector(that goes into the ecu).

any suggestions

 

I would say your best bet is finding someone parting out their car....and just have them cut off the connector with the wires still attached.....

you also will definately need a wiring diagram

 

I hate to be the bearer of bad news, but what you have ahead of you isn't going to be fun. I have gone through almost all the same problems that you have over the past two years of owning my car.

So here's what I can recomend:
1. You should give that thing a bath and use a good degreaser and a pressure washer. You know where the problems are so there is no reason toleave things oily.
2. That first connector looks like the temp sensor plug- rob one from a salvage yard (if you have one close by that lets you look for your own parts). As for the black one, if no wires are broken there are some electrical cleaners that will nutralize the corosion and then dab it with some electrical grease to keep moisture out
3. Add to your list of parts a new timing belt. It might be a good guess that if these other maintainence things were not taken care of then the timing belt probably wasnt changed yet either. And since you've got to flush the coolant system your might as well upgrade the water pump (usually comes with a good t-belt kit like the one from ECS).
4. It is my opinion that the $500 estimate parts cost someone else suggested is quite low. Be prepared to spend a lot more... especially if you need to buy some tools (do you have a torque wrench?). Audi's have a few odd size fasteners too. And you'll want to invest in a good shop manual. The DIY are good but sometimes aren't as thorough as they should be.
5. Since it doesn't sound like they hooked it up to a computer to check theCEL code you'll want to have that done too. I'd bet you have some dirty injectors and/or bad coil packs. Sometimes it's not the milage that effects these cars it's the age. Dig deep into those pockets.
6. Keep in mind that the car is way over-engineered. If there was ever a book that anyalized the psychy of the german engineer during the mid to late ninties I think I'd would've bought it. During your adventure you will ask yourself many times "what were they thinking when they designed this..." and there will be no good answer. There was just some down-right stupid things done when building these cars (and it probably still happens today).

Above all- be patient... and don't drink the beer while you're working. Only after you're done for the day.

 

thanks for the positive feedback, really appreciate it....

If you look at the last picture, you can see coolant residue in 2 of the connections which migrated from the Coolant temperature sensor(2nd to last picture) throught the wire and through black connector onto the ecu pins(which i cleaned out with isopropyl alchohol)

As far as the waterbelt and timing belt, i had that changed last summer when my serpantine belt broke.

I have a bentley manual, as well the vag scan tool. As for tools, I do have a torque wrench, torx set, ratchet and socket set. Any other tools i should get?

When im cleaning my car,I can just hose it down with pressurized water after covering the wires/connectors and alternator?

 

Would the oil cooler o-ring or the oil cooler itself be causing this leak?
