Hello Experts,

Just wondering, Does any one here experience a wierd behaviour on Rev gauge while on a not so steep downhill?

Basically, i own an Astra GTC 1.4T Auto transmission and when i'm doing a downhill, (doing around 40 ~ 60 mph - rev around 2000 rpm) and apply brake to slowdown, the engine rev goes up to 3000 ~ 4000 rpm.  Is this kind of normal?

I asked few Automatic car drivers (Jaguar XE owner and a BMW 3 Series owner - all 65 plate), and they said they haven't experinced such 

Hello All and thank you for reading through this thread.

I have a GTC with the A14NET engine. My turbo is not building enough boost, I've done some testing that I'll list below, please advise on what to do next as I'm running out of ideas.

Using the OBD II and Torque Pro app I'm monitoring Turbo boost and Intake Manifold Pressure.
I have two solenoid valves as I thought this was the problem. 
With the solenoid connected to the wastegate, the car won't boost more than 4-5 PSI triggering a

Could someone let know what size brake discs are on the GTC  1.4t  120 2017. 

Thanks

Hi all looking for advice

My Astra has recently started having overheating problems, Its had a new Thermostat and the waterpump has been removed and checked and is functioning correctly but it still seems to overheat, It'll sit happily on 90 during idle but after 3-5 minutes of driving it'll overheat and creep upto the 110-130 mark and advise the engine has overheated and to idle the engine. I was wondering if anyone else has had an issue like this and what my next steps should be?

Hi everyone,

Car overheated on Saturday, checked coolant level and nothing remaining in reservoir. Topped it up and made it home. Not easy to see where the leak is coming from, I think it may be the water pump, which I believe is a known issue on these cars. 

Taking it to a garage tomorrow. If is a water pump, what work would usually be completed additional to the pump replacement. Timing belt? Tensioners? 

Whats a reasonable price for water replacement?

Cheers

Does anyone know what the part number is for the Oil Cooler on an Astra J 1.4T (2013) as mine has a bad leak

Hi Everyone, 

My 2017 1.4T with just under 50k miles on it has started to make an engine noise, like a chudder.  This is at idle and increases with RPM.

Ive captured it on video. Wasn't sure best way to host the video so I've got a

Hi,

I currently keep getting a underboost error on my 1.4t.


I am looking to clean my egr valve as the error points to that. But I can find naff all about the valve on this engine. Where is it and how can it be removed? Anyone got tips or even better a link?

Does the egr need to be deleted in the ecu if blanked on this engine?


Thanks,
Ben
