S Type 2.7 auto (2007) Diesel hard to start from cold

Recommended Posts

My 2007 2.7 diesel S Type SE is getting harder to start when cold.

It cranks over very well (new battery a few months ago) but just takes a while to fire into life.

I have no warning lights on the dash. The glow plug dash light goes out as it should do and all else seems ok.

The car runs very well and has also had both EGR valves replaced a few months ago.

I have tried a bottle of Forte Diesel Specialist Injector Cleans (400ml) in a full tank of diesel but the tank is now in need of a refill but there has been no improvement.

Has anyone had similar problems and if so how did you cure it please?

Keith

Hi Joe, Thank you for your reply and advice.

I had assumed that were it glow plugs, there would be a change with the glow plug light on the dashboard.

Many thanks

UPDATE

 

Problem solved - at a cost of £27.95p

I replaced the fuel filter with a FRAM fuel filter. It took approximately 15 minutes and did not require any priming of the new filter in any way. It took a while to start after the change but once started it has been fine.

The existing fuel filter had been fitted in Nov 2018 (one year ago) and had done a total of 4,300 miles. However, it was a 'no name' fuel filter that came together with a service kit.

Before the fuel filter change my S Type 2.7 MPG had dropped from 34.4 to 33.7 in a couple of weeks - it has now returned to 34.4 mpg in a couple of days.

Hi Keith,

 

are you saying that changing the fuel filter cured the cold start problems ?

I have the same engine which is hesitant to start and then runs rough for a minute or two until moving off.

However, this only happens when the weather turns cold and first thing in the morning.

Many thanks,

Hi Ross, Initially yes. I read that poor fuel filters can clog up quickly and I checked back on my records for my car and found that I had bought a 'no name' (unknown source and make) fuel filter that came with a service kit bought from Ebay. Although it had only been on the car for less than one year and had done just 4k miles, I replaced it with a FRAM filter and the car started much quicker. Since then the car seems to start quicker that it did but still take rather longer to start than it should.

Hi Keith,

It is possible that the battery needs more regular charging, and also possible the the fuel system needs a cleaning additive.

I have an s type with the same engine and the same year and also live in the West Midlands.  I use premium fuel plus  an additive [Millers Eco + diesel]  both of which seem to be doing a good job.

Regards,

Peter.

Hi Peter, thanks for the reply to my post. I had a new battery a few months ago and regularly use Millers Eco Plus but it is still hard to start, I now have an additional problem in that the electronic parking brake (EPB) cannot be applied - I've tried the usual reset (battery disconnect) and also by disconnecting the two multi plugs into the EPBCM (control Module) but to no avail. The handbrake will not apply (Code C1802) so I'm now working on that as well. I suspect a seized rear caliper.

I love my S Type 2.7 and it is certainly keeping me busy lately!!

Hi all, just read the bit about checking glow plugs and thought I would add this warning. Couple of years back I had a Hyundai i30 which got hard to start in cold weather, suspecting faulty glow plugs I took it to my local garage to get them changed. After changing the plugs the engine rattled, you got it, the tip had snapped off one of the old plugs and was rattling about in the cylinder, resulting in a scrap engine.

Fortunately there are decent honest garages around and they accepted the mistake and fitted a replacement engine at no cost to me, I gather heater plug tips do occasionally snap off on removal so check properly before starting the engine again.
