kbdrim: I know this isn't on the topic but I just found this review of Audi A4 and it has pretty much scared me off the car.

I know you are a great Fan of Audi however its difficult to believe some many people could be wrong in their assertions. I want to use the car in Nigeria so Im concerned about its reliability. Pls advise Sienna. Thanks

Siena:

One of the reasons I've advised against the 1,8T versions. Cheap on gas, but turbo replacement and sludge issues (caused by mixing synthetic and mineral oils) can be expensive. 2,0I4, 2,4 / 3,0 V6 are best.

The items in green are minor niggles, which will afflict any modern car that runs on Control Modules. Oddly enough, the Audi enthusiasts in North America and Canada love the 1,8T. Personally, I would go with a V6 any day.

kbdrim:
Thanks so much sienna
Im Looking at getting a 2002-2003 a4 with a maximum millage of 100,000 miles from Germany. What would you advise I look out for in the maintenance history besides change of Timing Chain, water pump and clutch? I do know regular maintenance is what keeps most cars great!

platinumricky: @​ siena , why do U̶̲̥̅̊ prefer torque values in Newton metres (Nm)? I think it will be better to use Lb ft (pound ft) since majority of the automotive publications (motortrend,jalopnik,wcf,autocar,autoweek,Car & driver etc) use this- it makes it easier to compare and contrast. This is just my opinion though...

Most tuning houses here use Newtons to express torque, Audi and BMW do the same (all my Owner's Manuals express torque in Nm too). What I'll do from now on though is express the torque values in both Nm and lb-ft, if this'll help.

Sorry Siena I made a mistake in the model year

No worries, bro. The data for the 2007 model year still applies.

skeletine: @Sienna, sorry to derail thread. I drive a 406 (EW10) engine but have had power steering issues for the past 2 years and tried up to 4 pumps (all tokunbo) along the way and still no luck. am presently considering buying a new one but I want to be sure its all about the pump. Kindly advise. Regards

Siena:

Hey bro, when you say you've been having power steering issues for the past two years, what exactly do you mean? Leaking? Stiff steering? Noisy pump / steering operation in general?

Siena:

Bro, what spec is your car? Is it from the US or Europe?

Siena: Sammiejo's vehicle data - Kia Soul.

Fuel type: Petrol.

Sammiejo: Please whats the meaning of Naturally-aspirated?

Siena:

A faulty crank sensor would certainly cause difficulty in starting, and stalling in service. Faulty O2 sensors will cause poor fuel economy, but not stalling. If they're faulty, the ECU doesn't get any signals, and the fuel system simply reverts from closed-loop emission control to open-loop.

Items that could cause stalling in service are:

01) Faulty crankshaft sensor.
02) Faulty camshaft sensor (if fitted).
03) Faulty coolant temperature sensor.
04) Faulty fuel pump relay.
05) ECU power interruption (wiring, control relay fault).

You had a crank sensor replaced - was it a new one? If yes, was it a genuine item, or a patent part? Crank sensors also need correct orientation to function properly. If it's too far, or too close to the trigger wheel,the engine will have running issues.

I think a scan is in order - and please don't buy any more parts, untill you at least have some codes to go by. Random replacement of parts can chew through your finances in a very short time. If you pull any fault codes, don't have them erased, and post the results here.

I wish you all the best.
