  1. Interesting thread revival - I solved the problem over 3 years ago by p/exing the Octavia with a Merc C Class Estate !!!!
  2. My local indy tells me that compression on three cylinders is circa 195 but is only 135 on the fourth (number 3). So suspect either a bent valve or carbon build up. If bent valve then I'm puzzled. VCDS confirms car not breached rev limiter, and the cam chain was changed 10,000 miles ago by the main dealer. It was replaced by what is still the latest version of the chain and sprockets. So unlikely to be that the valve has touched the piston because of the well known chain issue. And carbon build up typically causes misfires rather than compression problems. Wish VAG supported their main dealers with walnut blasting on DI engines as BMW and MINI do, but as usual VAG try and pretend its no great problem on their engines. I'm dubious about the real value of an "italian tune up" - that will not help a DI engine clear the valves of carbon as the injector ports are on the "wrong" side of the inlet tract. So fuel never touches the valves and thrashing the engine or using different fuel makes absolutely no difference to the carbon build up - its mainly a design problem and is one of the reasons for moving to dual injectors (both before and after the valves) on later generation engines. May ask for a borecsope examination before going much further. But am still interested in hearing of anybody who has lifted one of these cylinder heads and how much the work cost.
  3. Hi 2010 Fabia with 1.2 TSI engine. Cam chain replaced by main dealer under warranty 2+ years ago. 28,000 miles to date. Owned since new. Now got loss of compression on cylinder 3 - might be the dreaded gummed up exhaust valve issue. So head off and clean required at a minimum. Anybody had this sort of problem fixed by a independent, and if so at what cost? Car is only worth circa £3K as a trade in so unsure whether to reapir or not anyway. Regards Minimoke
  4. I don't know where you get 3.5 hours from. I had the official Skoda timesheet for this job attached to the invoice and its 5.9 hours. My main Skoda dealer charges £75 ph before VAT so this gives £442 before VAT and £531 with VAT. The reason I got a copy of the official timesheet attached to the invoice was that Skoda UK paid the dealer for the labour for the job, and I hardly think Skoda would let the dealer charge more time than they allow. I only paid a small fraction of the total invoice price as Skoda made a goodwill contribution despite being out of warranty by 2 years. I was told by the dealer at the time that the full price for doing this job at a main dealer would be £700 including VAT. I repeat this is a non trivial job (if done properly).
  5. Only £355 to fit a new timing chain????? I'd grab that offer with both hands. I would expect a main dealer to charge nearly £500 plus VAT for labour alone. Its a non trivial job to change the chain.
  6. All petrol you buy now has ethanol up to a minimum of 5%. If and when the ethanol separates from the petroleum you end up with an ethanol rich/water layer at the bottom of the fuel tank. This can start to happen within 30 to 60 days of the fuel purchase if the conditions are right. Its not a rare occurence but the eco lobby likes to keep quiet about it and the problems it causes. Look up "seperation phase" in connection with bio fuels. Ive just spent an unhappy few hours clearing this crud out of the bottom of the fuel tank on my bike. Thats whst got me thinking and asking the question.
  7. If it is a long service item that says to me the filter just deals with any crud in the fuel rather than with any methanol/water. .
  8. Do any of you knowledgeable people know if Skoda/VAG deploy any traps or filters in the fuel lines of their petrol engine cars designed to trap water in the fuel that can occur because of the ethanol content? The reason I ask is that I've recently encountered a couple of petrol engined cars (not VAG) that have become verey difficult to start. This has been diagnosed as being due to water in the fuel which can happen if the ethanol content "phase separates" from the actual gasoline.
  9. To get some perspective try reading this: http://gabriel.com/wp-content/uploads/2011/04/TECH-_01_09.pdf
  10. Which is exactly why I took the 2 year extension to the manufacturers warranty when I ordered mine. I would not run a DSG without a warranty, but sods law I've never had any problems with both the 6 and 7 speeders I have owned.
  11. Final point. I've just checked and they do have to drop the old oil to reach the crankshaft pinion. So you will have to add oil and filter to the budget for this job.
  12. Which is why I always use the fixed service regime on any make of car I own. In my opinion you cant beat a regular oil/filter change every 12 months at least. Cam chains are normally reliable and can do a lot of miles in normal service, but dirty oil is their enemy.
  13. Why on earth wouldn't Skoda use the latest repair kit? The earlier kits are known to fail again which is precisely why they issued a kit revision! You will require more parts than just the kit alone. For example there is special grease for the camshaft and sealent for the cam cover etc. Total for all parts and materials for changing mine by a dealer was £136 excluding 20% VAT. £100 to fit it????? Crikey, I know labour rates in Poland are lower than here in the UK but that works out at £16 per hour! As I posted in another answer it requires 6 hours labour. I'm not normally a huge fan of dealers, but in this case (and for peace of mind) I would get a dealer to do it for the reasons I gave in an earlier post. Whoever you choose my advice is get it done without delay. A rattling cam chain on these engines is indeed a potential timebomb.
  14. My experience is that changing the oil etc will disguise the problem for a while but the rattle will return. Personally I would not let an independent garage do the work unless they really know what they are doing. The latest repair kit involves changing both the camshaft and crankshaft sprockets so it is essential that both camshaft and crankshaft are "locked" so that the valve timing is not changed. If the timing is changed then the engine will likely go bang very quickly. I spoke to several independent garages at the time and both claimed NEVER to have changed a camchain on a 1.2 TSI. I think they really meant they didn't want the job because they didn't know how to do it. The main dealer who changed mine said their workshop had done loads - he knew immediately what the problem was when I took it in to be inspected and lodged the warranty claim with Skoda about 2 hours after I dropped the car off for inspection! Having said that the main dealer who I used prior to that consistently denied there was a problem whilst it was under warranty and it was "not a known problem". Just quote the TPI to any dealer who takes that line - they cannot deny the issue. I think the dealers have access to special tool from Skoda to do this job. I'm not 100% sure but I think the generalised tool they use to lock an engine when changing a cambelt is not suitable. Anyway these engines are camchain so they don't normally require a locking tool! So I would be inclined to take it to a main dealer. They know what needs to be done, have access to any special tools they might need and will have to warrant their work. The cost of the job on mine done by a main dealer was £700 (including 20% VAT). That includes 6 hours of labour. But I only actually paid a fraction of that. You may get lucky with a "goodwill" payment from Skoda if the car is out of warranty. Mine was out of warranty for over 2 years, but it had always been serviced by a main dealer. I think you will be lucky to get any contribution if the car has been serviced outside the dealer network. Best of luck. I would get it fixed without delay - camchain failures can frequently wreck the motor, and if that happens the cost of replacing just the chain will look very cheap! EDIT: I forgot to say that the cost does not include the cost of any oil. I'm not sure if they have to drop the sump to get to the crankshaft sprocket, in which case an oil change is obviously also required. In my case I asked them to do an oil/filter change whilst it was in the workshop (it was due an oil change the following month anyway) so I paid 100% the cost of the oil. This was included in the total invoice so I can't tell whether they would have had to fill up with fresh oil as part of the cam chain job. You will have to ask the workshop to clarify this point as it may add to the costs I quoted.
  15. Not sure about the Mk3 but they were just a push fit on the Mk2.
