Good Morning All,

Bulletin just been released by Vauxhall advising that for Turbocharged Direct Injection Engines there is a certain risk for Stochastic Pre Ignition (SPI). This SPI causes strong pressure peaks in the combustion chamber which may harm the piston ring lands.

Fault:

Sporadic metallic noise from combustion chamber, sometimes with short loss of power. Occasionally fault code 'P0300 Engine Misfire' is stored but not all the time. Engine Light might not even come on when power loss suffered. This may be the source of the engine splutter / short loss of power people are experiencing in 1.4 Turbo.

Affected Models:

Amongst the affected models are the two versions of the 1.4 Turbo in the Astra K (B14XFL/T RPO code LE1 and LE2). I have the 150ps 1.4 Turbo Astra K which is RPO code LE2.

Resolution:

Vauxhall/Opel/GM have developed a new engine Oil - Dexos 1, Generation 2 to reduce the risk of this fault happening. This new Oil is essential to be used for Astra K 1.4 Turbo. However up until this point only Dexos 2 has been available. The new Oil will be released in the final week of April 2017. The part number is: 95599877 which comes in a 5 litre container, larger sizes will be available at a later date. Model Year 2017 cars are shipped with the new oil in already.

In the meantime the bulletin states GM Dexos 2 MUST be used until Dexo 1, Gen 2 becomes available.

Needless to say I shall be having an Oil & Filter change last week of April and have already placed an order at work for the new oil.

Hope people find this useful :)

Hi would anyone know what oil they would have put in mine with a production date 7/06/2017 don't want to change the oil, only done 1500 miles with no problems, but if it's got the wrong stuff in will have to.
Hi
Yours will have the Dexos 1 generation 2 oil in.
I think the bulletin states that all new cars were having it put in before the bulletin release. The bulletin is at the start of this thread.

I've just got my astra back after 2 days of diagnosis they said they've replaced the "receiver".
I had a service theft deterrent system message now and then and won't lock after getting out of car.
I'm wondering if they've applied this update while it was in because it takes off now..might be because I had a corsa as a hire car!
