Tapping noise from engine renault grand scenic 1.9 dci

SOURCE: 2004 Renault Trafic 1,9 dci gearbox problem. I

had exactly the same problem with mine, its in my mates garage as we speak. he had to take the engine out open the gear box and check the bearings. All the bearings were worn !!!! had to buy a wole bearing kit, £170 . plus labour, lot cheaper than getting it reconditioned by specialists!!! they wanted £1000 for doing exactly what my mate has done for me. Hope this helps you!!!!!!!!!!!!!!!

have a look at renaultcustomer.com and howtomendit.com for an idea JUST how widespread this problem is - big campaign on to get victims to contact Watchdog, please join! Yes, Renault will charge £500-£700 to fix and may or may not help out with cost (small %) BUT you can get it fixed via some online companies - try Cluster Repairs UK or ECUtesting on Google. About £200 with either. Hope this helps - though Renault should of course be covering costs, so ring their Customer Care line and get a case reference first.

Try the relays under the bonnet fuse box 4 small black ones in a line, the first 2 from top cut of the fuel pump, and are a renowned cause of 85% of cranking without starting faults on the dci engine swap them over for the bottom 2 .
If it starts, buy 2 from Renault and fit
if the engine still fails to start the egr valve may be stuck closed starving the engine of air, its on the top of the engine at the air intake and has 3 bolts, remove it and clean it with carb cleaner then check its condition, if it appears ok, replace the cleaned one, if not you need a new one or the turbo will blow its seals and the engine will rev and burn on the engines own oil.
beyond this and your diy fixes are at an end without a obd2 code reader.

SOURCE: 03 renault scenic wont start when cold unless

hi if on engine starting and warmed you have no problems and no warning/malfunction light showing ? then i would suspect that trouble points to the engine coolant temperature sensor it tells the ecu to provide excess/choke to simplify? fuel as engine is cold so in simple theory you are trying to start with no choke as it was on old carburettor engines if you are old enough to remember ?? (joke) it was much simpler in those days however check the sensor and its plug is clean/secure and wires are ok ? when sensor works your engine fires up and runs withslight increase revs till warmed then settles to idle revsas specified in h/book this sensor is not the temp sensor that works the temp indicator guage it is a seperate sensor and larger screwed into either cyl head or block on the side hope this helps good luck

SOURCE: WHEN TO CHANGE TIMING BELT

The Renault schedule for timing belts on the Scenic is 72,000 miles or 5 years. This applies to both the petrol and DCI models as both have timing belts not chains.

However, please be aware that it is common knowledge in the trade not to let the interval go past 40,000 miles because these engines are renowned for snapping belts at any time after 40k resulting in serious engine damage.

Haynes (who are renowned for their service manuals on many models) recommend a maximum interval of 36,000 miles between belts on this model which is exactly half that of what Renault say!

This information from Haynes is backed up by experience and reports from the trade on the common and unfortunate experiences of customers experiencing belt breakage at 45 k and below.

Hope this helps. Please do leave a vote for the solution. Thanks.
