    Timing Belt / Engine Damage

    2015 Skoda Octavia Estate 140 4x4 Engine Code: CRMB
    P0016 CMP Sensor (G40) / EngineSpeed Sensor (G28), Incorrect Correlation
    P13D6 Cylinder 3 Internal Pressure Sensor, Implausible Signal
    P0101 Mass Air Flow Sensor (G70), Implausible Signal

    Had the 3 faults come up on VCDS Scan and started with P13D6. Replaced the Glowplug but still had fault. So, as I was getting know where with it took the car to an Independent VAG Specialist that I use for the major work on all my VAG cars such as Timing Belt, Clutch etc. Drove it to them, around 15 miles, and left it with them. When they checked it out they found a large oil leak in the timing case area and the timing belt smothered in oil. Not only that but it appeared that the belt had 'jumped' 3 teeth! They were not prepared to run the engine to see where the oil leak was because of this but agreed to replace all the oil seals they could to hopefully cure the oil leak and fit a new belt kit and water pump then check out for any further damage. They did all that, set the timing up and started the car, which, appeared to run ok at tick over? However when they took it out for a test drive they found it was 'down on power' and when they returned and put it on their diagnostic machine (Haynes Pro?) it showed an EGR fault while driving but not at tick over. There machine came up with a code 233-12 but as this model has 2 (parts) to the EGR, one at the rear of the engine at the turbo/exhaust end and one at the front of the engine it could not identify exactly which part was at fault! They rang the parts supply, TPS (owned by VAG and only supply genuine parts) to see which part they supplied most of but they told them neither. So currently their 2 possible diagnosis are, 1) one or both parts of the EGR are faulty and require replacing (the rear one alone will cost around £1k with labour) or 2) possible valve / engine damage due to timing belt being so far out. They did say that they had never seen a vehicle that far out that still ran! Their recommendation was to take the car to the Skoda Dealer and run it on their factory diagnostic machine and obtain the report as they should be able to identify which part of the EGR is faulty if that is the issue. The sting in the tail however is, while driving the car home from the garage, which did start and initially run reasonably well began to lose power after about 3 miles and eventually stopped altogether and would not restart. Recovery firm brought me home and it now stands outside the house not going anywhere. Was thinking of finding somebody that could come and do a compression test (believe it can be done by removing the glow plugs) to see if that identifies any engine damage. Quotes for a replacement engine are coming in at between £2.5k and £3k so need to be pretty certain what is wrong before making a decision.
    Apologies for going on for a bit but wondered if this was a 'safe' engine or had any suggestions what could be the cause?

    IF the engine is terminally damaged, the only way I would deal with it is by fitting a genuine Skoda exchange unit, part number 04L 100 090 EX which retails at £4350.59 including VAT and comes with a two year Skoda backed parts and labour warranty. It may sound expensive but what you get is very comprehensive, a fully factory built engine complete with injectors and glow plugs and most importantly comes with the revised camshaft drive module which replaces the horrendous original; a friend of mine once described the noise as being like "a skeleton wanking in a biscuit tin"...

    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    Thanks for the reply, but the quotes I have 2 of them include a 2 year guarantee, plus (if they are to be believed, not may any investigations) one of them professes to actually supply and fit engines for Skoda Dealers? The car is a taxi and has 131,000 on it and a lifespan of a couple of more years at best so although not looking at a cut price job not willing to spend a fortune. Besides, through my contacts, I could nearly get a suitable replacement for not much more than that cost.

    UPDATE:
    So after a lot of head scratching and back to basic thinking have (sort of) identified the issue? By removing the Oxygen Sensor from the top the engine started, ran and went up to 2500 rpm (around the maximum when idling) then would tick over quite happily with exhaust gases coming out the oxygen sensor hole! Garage had it back for further investigation which with the addition of a lift were able to disconnect the exhaust down pipe but no change so the diagnosis is the DPF is completely blocked creating excessive back pressure thus non starting or starting and running for a few seconds. So it's looking like removing the DPF and either having it cleaned or fitting a secondhand unit then probably moving the car on for part ex!

    Would anybody have some information on removing the DPF on this model as to me it looks like it may come out the top of the engine bay as unlike earlier models the front/down pipe of the exhaust is not attached to the DPF unit? A quick check around highlights the clamps on the exhaust, turbo and exhaust cooler along with a couple of brackets, pipes and electrical connections?

    In addition I have a long list of possible part numbers for my car so trying to identify exactly the one for my car either with the dealer or when I get the DPF off the car. Engine code is CRMB.

    These are awful sods to do, bad enough on front wheel drive but add a transfer box and prop shaft! We did a 4 Motion Golf 7 and it nearly would have been easier to drop the subframe and transaxle down, it took the mechanic nearly all day to get the thing out. Send it to DPF Clean Team in Hinckley, they have sorted out dozens of basket case DPF’s for us.
