    Hi all, some conflicting information on the web, with some obviously from people with little knowledge but lots of opinion - hoping that this is the right place for facts and help...

    Relation has had a major bxe engine failure - con rod out of crankcase without warning. The car is 58 plate 99k miles and full history although not VW, with oil change every 10k not long life regime, never had any problems etc.

    It seems others have had similar failures with the bxe engine, the RAC man attending only had to look at the data plate and symptoms to diagnose what had happened.

    So the questions:

    1) What is the cause and is it completely random on any bxe engine between 2005-2010? I ask as sourcing a used engine, are there specific serial numbers to avoid, or is it just a question of luck for the inevitable that it happens again?

    2) How much would you expect to pay for a secondhand engine plus installation? Ebay for example lists engines from £300 odd up to around £1,000. How much is the labour to fit?

    3) Is there any reliable Diesel engine VW make for the B6 Passat? When buying the car dealers and the community advised to steer clear of the 2.0 PD which had injector, oil pump issues etc. Certainly the 1.9 was PD described on forums as one of the most reliable engines made - well not in our experience and many others! Is the later CR 2.0 110&140 engine and 1.6 CR any good or does that have problems too?

    It's a negative post perhaps, but after such a bad experience of a VW after going to such lengths sourcing a low mileage and immaculate car at considerable cost, good advice is appreciated to avoid making any more costly mistakes and experiencing such unreliability.

    Thanks and regards.

    It's poor quality bearing shells .

    The upper wear through and spot weld to the crank sending the leg out of bed .

    By all means source another BXE or BKC , just renew all the bearing shells.

    The Achilles heel is the modern con rod bearings, they are very hard to reduce wear but they eat through the aluminium layer and this picks up on the crank and the powdered metal sintered rods are brittle so when given unusual side forces, they throw their toys out of the pram. Upper right, lower left

    Hi there,

    Thanks for the replies and explanation... Hmm definitely seems to be a resident design flaw then, given description and the number of posts out there of failures.

    Have had a replacement used engine fitted, garage didn't offer to do this change of shells suggested, but I guess it would have worked out significantly more expensive on top of an already hefty bill.

    So... are there more reliable VW diesel engines for the Passat that are recommended, or are they all fragile in different ways? The same age 2.0 PD (was originally told by dealer to steer well clear of this engine) or the later 2.0 CR in 110 or 140 HP? Is the same engine also in a 1.6 CR version in later B7 Passats any good?

    It is probably best in the long term to search out another model of better reliability, but as the fragility of the bxe 1.9 engine is probably known it will be a difficult sell.

    Cheers

    They are all reliable, when I started in this business 40 years ago, any car with 100K miles on it was a talking point, in the early days of Beetle production, you received a gold pin from VW if you managed 100000 KILOMETERS! In what was Safer Motoring magazine they had a 100000 mile register and you had special mention if this was on one engine! In the 80's we we regularly had to put new con rod bearings in Golf GTI engines and the 0.9>1.3 was terrible for rattling rods, the thing was that they were so much cheaper and faster to fix, I could do a Passat head gasket in a day including going to the engineers, going back to work and waiting back, going back to collect and rebuilding and out the door by end of play, now it's three days work if you are lucky and the cost can write off a 6 year old car. Much of the trouble is due to emissions regulations, these have made oil not what it once was, no matter what BS the oil manufacturers give us, it is why most engines have now moved over to roller follower cams as flat tappet cams are a liability. We literally nag our customers into 9300 mile oil changes and for us to see this con rod failure on a customers car is unheard of. At 100K miles we do recommend the BXE engines have their rod bearings replaced, not many people do but we still don't see any failures, as I have said on here we have NEVER seen this failure on any engine, just heard about it.... a lot!

    Enjoy your 1.9 while you can.
    Anything you will get next because you will have to apply for emission standarts of EURO 5 or greater will hit your pocket harder.

    2007 Passat b6 2.0 tdi BMR DSG

    If you buy a diesel and want to avoid the low emissions zones coming soon all over Europe then it will have to be EU6, petrol engined cars are OK from EU4.

    Hi sorry to drag up an old thread but I have a bxe engine 2007 1.9tdi on 68000 miles, I'm scared of the dreaded con rod out the side of the block issue and want to do what I can to prevent it. Are the new bearings from vw modified to prevent this happening?
    Any advice appreciated, thanks
    Regards

    Never apologise , it's as important and still current as the 2.0 tdi oil pump drive debacle .

    Hi mate, yeh I've seen a few but I'm just wondering whether to replace my bearings with vw genuine ones ? They seem to have a superceded part number for the upper bearings so do you know if they are modified to over come the issues of them wearing out so quickly and popping a rod? Thanks ��
