4 months into ownership now and I am now contemplating a remap. My local remap specialist has a good reputation and offers the following: http://www.dynoremapping.co.uk/remapping.php?m=Volkswagen&mod=Golf(V)&ver=1.9L 8v TDi

I have the 1.9 105bhp model so would see 135bhp after remap and a jump in NM of torque from 250 to 310.

Has anyone else remapped this engine and if so, is it going to be noticeable enough to justify the cost?
Any real world effect on MPG and oil consumption?

Cheers

Howdo.

I remapped a 130PD which is the same basic engine, on a Bora, at 98k. Ran it to 130k no issues when I sold it.

Also remapped a Focus from 115 to 130bhp, but more importantly 35lb ft more of torque, made a big difference. Did that at 39k, again no issues when I sold it at 67k

I'm going to remap the C220Cdi next year too.

Both Focus and Bora got BETTER mpg on the cruise.

As long as you respect the limits of turbo and clutch, remaps on a diesel are always worth doing. You'll be fine clutchwise as you'll have the same as my Bora, rated to 405Nm.

Being a diesel you won't notice a massive difference on 0-60, but you WILL notice it in 3rd gear pulls up sliproads and when overtaking. Then you'll see it's money well spent.

Thanks. The in gear pace is one area that my Golf as it stands is lacking. The power arrives in a surge which is over far too quickly before needing to change gear. I know diesels don't rev but a broader spread of power would be nice. Acceleration in 5th at around 60 is pedestrian but dropping to 4th means lots of revs and noise!

I've got the 2.0ltr 170PD engine and had it remapped a while ago. The difference will be very noticeable in your spec. My mpg is now regularly in the mid 50s which for a circa 200hp engine I thought was pretty good. I imagine you'll see a good increase also with mpg and the low down torque. As Yugguy says a straight forward stage 1 remap is a no brainer on diesels as you'll get gains in all areas

You will notice the power hike. Insurers are picky about any kind of modification but most will accept a remap especially if done primarily for an MPG improvement for a modest premium loading. Talk to them first though, some regard remaps, chips and piggyback ecus completely differently.

Thanks. I'll have a chat with them tomorrow to see what they think. I have emailed dynotech asking a few questions. We have just got back from a family holiday in Scotland and I have felt a bit spoilt driving my dads 2012 Audi A4 Avant 2.0 TDi SE Technik 170PS! So much more power!

Spoke to my insurer (Sainsburys) yesterday and they refuse to cover such a modification. Rather than cancel and go elsewhere, I will wait until renewal and get a number of quotes that will cover the modification. Not in a rush at the moment.

There is an insurance company on here who might be able to help but the name escapes me, I think it's Sky or Prestige. I use Adrian Flux for my heavily modified car and have done for several years now.

Most of the "insurers" mentioned in the last few posts are actually brokers. It's always worth finding out who the broker is going to get to underwrite the policy and then approach them direct. You may get a better deal.

Not necessarily on modified cars, a lot of these are broker schemes exclusive to the broker. The rates depend on the claims and losses through each broker so having a mature client base really helps.

I quite like and support the local insurance broker.

In all other cases you may save 10% or so going direct but you'll have a nightmare at claim time and often the policies have restrictions that a broker wouldn't let them get away with. You get what you pay for in everything in life but the hope is that with insurance you hope you'll never use it.

My local broker www.millardsinsurance.co.uk was cheaper than the directs thanks to their in house schemes and deals with insurers.

Personally I'm happy for a broker to take his cut for the paperwork and staff and will get help and support when I need it and not spend hours on the phone myself.

Had a remap done on my 103 bhp version and I could tell the difference before I was a 1/2 mile up the road. |B Go for the performance upgrade rather than the fuel economy version and you'll still get better mpg.

I am re-visiting this topic again. Insurance renewal date is 14/04 which means the renewal documents will be along in the next few weeks. Admiral came out at £5 more per month than I am currently paying with Sainsburys (who refuse cover for the mod) but for that I had to up it to £500 excess from zero.

Flux were about £20 more per month so I laughed and put the phone down. Tried Sky online quote which refused to quote online and it said they would phone but never did. I might try phoning them. You would think I was modifying a Supra to 1000bhp not a run of the mill Golf!

So, just out of curiosity, if I wanted more than the 30bhp gain, would it be wise to go for an upgraded clutch and flywheel? Any idea on the cost of such an upgrade?

Cheers

What you planning now then, Turbo upgrade?:woot:
Darkside Developments do upgrade kits to give you an idea of specs and price

Thanks. Not turbo, it's just that there are greater levels of remapping available.

I read on one forum that the standard clutch can handle 180bhp. I find that a bit of a stretch and I dare say that there are many other components to consider with such a power hike.

Just bear in mind then the extra stress and increased potential to breakages on engine components like the turbo. Fitting better Turbo kit is far safer way to increase the power rather than pushing existing components past their limit with stage 2/3 remaps especially if it's a daily driver. You will need to consider upgrading inter cooler and associated pipework, injectors, fuel pump, turbo hoses etc etc and obviously mechanical bits like clutch, brakes and probably suspension to handle that much power. All doable of course and will be a lot of fun.
*Edit*
Just seeing it's a mk5 Golf I wonder if the components from the GT170 would transfer across? Worth investigating

I didn't know the 1.9 units had such a highly rated clutch but even so, if our friend here takes the remap past a regular performance stage 1 map he'll be getting awfully close to that figure anyway. I wonder now also how much they can turn that standard turbo unit upto, 180hp sounds a bit far fetched to me unless they really really detuned that engine at the factory
