Audi A4 2.5 TDi or a BMW TDi ???
#2
The audi a4 cabs are a lovely car and imo better than any of the others,iv had 3 cabs 3.0 sport,2.4 sport and another 3.0 sport also and rs4 cab brand new in 06..
the 2.5 tdi though is not the best engine at all!!although will go on for ever its just not great on fuel ,its heavy and doesnt offer great perfomance compared to others..
If it has to be a diesel then the 2.0 tdi is far better but for example the mpg from the 3.0 petrol isnt much worse than the 2.5 tdi and is a lot lighter smoother and far more powerfull..
If you can afford the new 05 onwards tdi cab then the 2.0 tdi is either 140 or 170 hp std and with a map will give nearly 200 hp and 350 lb ft and over 40 mpg and is by far the best allround choice..HTH

so in your opinion of having them deffo go for the 2.0L I want something thats good on fuel as the wife is doing a fair few miles now

Yes mate an s line 20 tdi is an awesome car,if twin pipe at back its a 170 hp and if single its a 140 either doesnt matter as mapped they are the same ish power any way but deffo well worth doing..
The 2.5 tdi is 163 hp iirc but as said lazy heavy and thirsty the 2.0 tdi if driven carefully with map will see a genuine 50 mpg and a near 40 when getting fruity..
The s line really is a nice car so find a nice one and enjoy !!

Couldn't say it any better myself
I've had 320cd m sport and a4 2.0 tdi s line , there is night and day difference ! Audi is 50 times better, I'd have anouther Audi tomo .

i own a 2.5tdi audi cab mate pic in my sig , dont bother if im honest its lovely really is but between 28-44mpg i had to have a replacement engine as the cam lobe sheared, then after that derv pump went down,
its not quick at all if im honest but very very comfy and pretty
i have a years worth left to pay on it then i will look at something else definately get a a4 cabriolet but in the 2.0tdi guise

Exactly why i put him off the 2.5 tdi engine as all the things youve stated are very common!! a bad engine that one..
The 2.0 tdi though is bomb proof!!

seems to be a problem from 2005-06.
2.0TDi Oil Pump / Balancer shaft problems - the definitive guide! Audi VW Skoda SEAT
2.0TDi Oil Pump / Balancer shaft problems - the definitive guide! Audi VW Skoda SEAT
Maybe this should be a sticky? Will clear up most of the common questions asked on all the VAG forums (ive been through them all while doing my A4 BLB balancer unit/pump):
I spent some time on ETKA a while ago trying to figure out why some 2.0PD oil pump drives fail and some don't. The BKD, AZV & BMN 2.0 engines (which is what found their way into the 2.0 PD Octavia, A3, Golf, various Seats) used a chain driven oil pump very similar, but not identical, to the old 1.9 130hp PD engine. This never seems to give any problems. I can tell from ETKA these engines don't have a balancer shaft which I think is the key to it - it's the balancer shafts that cause the problems on the 'posher' VAG 2.0 PD diesels eg Passat, A4, Superb. By trying to make the engine more refined for the more expensive models they destroyed it's reliability in the process.
Very briefly, the 2.0 PD differs from the 1.9 in having twin Lanchester balancing shafts which contra-rotate at 2x crank speed. The first engines used a chain drive which was a complete disaster (pictures on this website) and the later engines a gear drive. All 2.0 PD got the geared drive towards the end of 2005.
The problem with the 2.0 PD engine is the drive from the slave balancer shaft to the oil pump, which is a piece of 6 AF hex bar which has inadequate engagement depth with the grooves in the slave shaft. It's the torsional oscillations caused by the balance shafts which destroy the oil pump coupling (the 6mm AF bit of hex) and the chain drive to the balancer shafts before the gear driven systems came out, though these still give problems with the hex key rounding. Think washing machine -> unbalanced load -> keep doing it = new machine.
PSA had no problem at all driving their oil pump from the slave balancer shaft on the bigger HDi engines so it's poor VAG engineering at the bottom of it all - as usual.
As I said earlier, the problem is with lack of concentricity of the drive socket into which the drive rod/hex fits. Since I've started looking at this problem, I've seen three cars where the drive socket is off centre by at least 0.1mm. In engineering terms, this is a massive defect. Since I've starting checking the concentricity, all the drive sockets in the failed units were off centre, but all the replacement balancer units were dead centre and have not led to a repeat failure in the people i have spoken too. Some replacement balancer units have now done 100k+ miles according to some garages.
So, to sum up. You will get this problem at some point if you have a 2.0TDi WITH balancer shafts. If your 2.0TDi does NOT have balancer shafts, you will be ok. If you fit the lastest balancer shaft/ pump assembley from VAG it will more than likely cure the problem for life as they have made the hex longer and centered it all properley.
Dealers do not admit any liability. You will not get any fiscal help with changing for the new balancer/pump unit. The fact that VAG have released and re-released different pumps/shafts/engines etc.. is "purely coincidence", according to Audi customer services! I am voting with my feet and never buying a VAG car ever again, they are not worth the extra money and the customer service is a disgrace. If you have this problem yourself, STOP driving the car. If you havent blown the turbo and your engine is not rattling you may get away with not replacing the lump, just the pump/balancer. If you havent had the problem yet and you do have a balancer shaft engine, I would advise either changing the balacer system now or getting rid of the car. From what i can assertain, CR engines are safe. Anything before that..well, Audi/VAG wont say exactley when they started to fit the units that actualy work properley.....
GOOD LUCK!
N.B. Thanks to all the contributers from across the VAG network and various garages

iv had audi 05 and 06 and seat leons 05 and 06 and vw touran 04 and 05 etc with never a problem although i have had the egr pipes break on a couple that is very common on the 2.0 tdi
didnt know about any other problems

Awesome motors.
The 270/320 Cdi mercs are top engines,tune easy too as I expect Danny will testify.
There's that drift merc on an old 1993 6 cyl 24v engine with a huge turbo doing the rounds so there are good 6 cyl motors out there,but perhaps not v6.

Yes the 233hp(240ps) as std is the one to have,do between 280-300 on a good map and 45-475lbft depending on year..
I have the 2009 model which has the latest ecu(upto last year anyway)and that is even better and cheaper tax(lower kgm)..
There is some awesome 6 cylinder tdi out there as said the mercs and bmws too
cheers danny
#32
well I picked mine up today and had a great drive home down the M6,loads of powers handles well and looks great,seems good on fuel as well,just to say thanks to all for the advice on which one to buy,my wife will be well pleased with it as the kids are
might have it chipped to see if gets any better on fuel,theres some on e bay with some very TALL claims

you can get around the 190 hp mark and 340 lb ft mark without trouble mate and an evoloution dealer will be the one to use so talk to stu and ask for your nearest..the mpg will go up loads too
The power will be circa 190 hp and the torque over 300 lb ft with better mpg..it will transform the car but as above mate expect problems if keeping for a while..not map related..

when i got my B5 2.5tdi it had done 120k (2005 ish)
i thaught it was fast and i wanted it mapped
got the car back and it flew! But i was told it was not mapped yet, but had the MAF replaced as it was fucked.
they maped it a few weeks later and fuck me, so quick for what it was (Quattro manual)
blah blah, put a bigger turbo on, EGR blank off and cleaned both inlet manifolds (another huge gain)
bigger injector tips/nozzles and mapped again
it did 212bhp and 404lb/ft and was just over 198,000miles by now
only things that failed was PAS pump and the old turbo started having sticky VNT trackts (several MAF`s but thats part and parcel i guess)
the car ran 14sec 1/4`s all day long and hit the governer in 6th at about 148mph on 245/35 18 tyres
midrange torque from 2000rpm@34psi was phenomenal, and still returned cracking fuel economy, once remapped it was cracking on diesesel!
and had more chatter than your mates mum on speed

Glad I could help , after seeing that photo Im going to have a look at that s4 cabby I was offered it down to £6200 , if I don't like the fuel bill I'll just sell it .

Sounds the polar opposite to my one then , its like a slug , doesnt go well and has no urgency to it all , lol .
Danny drop me a pm with the re-map price when you get it for me please then .
