Hi all, I find the 75 bhp on my 500 multijet a bit tame to the 95 I had on my Corsa c CDTI, I can get a remap to 95 bhp for £250 at one of my local tuning outfits. Your thought on this would be greatly appreciated as I have never done this before. Are there any pitfalls or drive train implications? Has anyone done it?and how was it.? I apologise if this has been asked before. Any input welcomed. [emoji2]

I've thought long and hard about doing the same. ATM I'm using a tunebox. I can't compare it to a remap as I haven't made the jump yet, but I can honestly say it's made a noticeable improvement over stock with no negative effects (touch wood). More torque so better off the line and a slight improvement on mpg. I have noticed a fair bit more smoke when the dpf is doing a regen tho.

If you have the money I'd say go for it. If cash is tight maybe go for a £40 tune box and see if it does the job. There's lots of pros and cons for either, and lots of discussion.

How often does yours do a regen kekybobo.??

It's hard to say, but I suppose about once per full tank.

Recently I've been doing about 50miles a day (although today I did 100). On a 50mile day it would be about 30 on the motorway and 20 in the town with 5 or 6 full stops with ignition off. Id usually achieve about 350 miles per tank with the Speedo telling me an average of around 60mpg. This week I've done better. Ive just passed the 365 mile mark and the petrol light has just come on.

With the box unplugged it regens about the same interval but with less smoke.

When I do notice the car starting to regenerate If possible I drop a gear and gun it. The full regen then takes about 30secs. Maybe it's just the illusion of more smoke as I sort of force it's hand.

I steer clear of supermarket fuel and use a dpf cleaner additive every 4th or 5th tank. I'll be adding some this weekend.

Thanx for the heads up on this. I will look into it. Easy to fit?

Simple. Literally a minute.

Ok, I decided to take your advice. I have ordered the tuning box on ebay, £38 and free postage from Germany, it claims to give 95 bhp

You have saved my over £210, if I get 95 bhp and a wee bit more mpg I will be happy.

Nope [emoji12]

As a cyclist living in a steep valley, I absolutely detest diesel cars.

No matter how new or how old or anything, they are smelly and awful going up the hill out of the village. Long 20% hill on a main road.

If you increase the performance, you must also increase the muck chucked out.
It's not visible or black, but if you are overtaken by a diesel car you breath in the stuff. It's smelly and filthy to inhale and to taste.

Sorry to put a downer on this, but the sooner we get rid of diesel cars, the happier I will be ............ and most other cyclists too.

I'll get off my hobby horse now. :worship:

hey maybe they should make fuel cheaper too. as long as europe has stupidly expensive fuel, i will prefer diesel!

Diesel cars most definitely contribute, But unless you address lorry's, buses, trains and ferry's at the same time it's not going to make much of a dent in reducing overall diesel emissions.

Yes you have to start somewhere but it always seems like it's the little man that has to bear the brunt first.

Current generation diesel buses and lorries use a different type of emissions control technology and are, perhaps surprisingly, much cleaner than most current generation diesel passenger cars.

Please don't get me started on trains, and, much worse, ships - particularly large container ships operating in international waters.

The scientific and environmental case for taking diesel passenger cars off the road now is overwhelming; the only case for not doing so is political; the cost of compensating the little man would be colossal and the cost of not doing so would be outrage and indignation from diesel car owners.

Current government estimates are that diesel pollution (from all sources) kills about 29,000 people per annum in the UK.

A little further research into the harmful effects of diesel pollution may both surprise you and alarm you.

My personal indignation is that all of this was well known within the scientific community during the period when national governments incentivised and encouraged folks to buy diesel cars.

Until they are either phased out or fitted with effective emission systems, diesel car owners can minimise the impact of their own vehicles by ensuring that they are correctly serviced, that the factory fitted emissions control systems are working properly, and by not attempting to modify them from their original specification.

I guess the only realistic approach is to slowly phase out diesel cars and incentivise people to go petrol or hybrid. (I wonder was the vw scandal one such way to put people off diesel).

Could they not use that truck and bus technology in cars?

A simple remedy would be if petrol was significantly lower that diesel. My local station currently has diesel at 109.8 and petrol at 110.2.

Yes, but at a price - selective catalytic reduction systems (that's adBlue to you & me) can get NOx levels far lower than the much less effective and more troublesome EGR systems used by the likes of Fiat and most major manufacturers, but it comes with a hefty price tag - and having to regularly top up an adBlue reservoir would likely put off many car drivers.

I think this is likely to happen, but the other way round - they'll change the fuel duty rates so that diesel is significantly more expensive than petrol. The difficulty is how to do this without penalising the cleaner heavy diesel powered vehicles with SCR systems and crippling the transport infrastructure in the process. One way around this could be to progressively increase VED for diesel passenger cars, and to impose an initial purchase levy on any new diesel cars not fitted with SCR type technology.

Having sort of assessed this problem (locally) over the last year or so, I can state quite categorically that busses and lorries and most big vans are absolutely fine.

It's every single diesel car that is the problem. Maybe the main issue with these is the driver?

Going along gently, they are fine and clean. It's when they accellerate hard up a hill or impatiently overtake that the smell and yukkiness comes out of the tail-pipe. If they could ease off and not be so desperate to use ever last drop of their powerful turbo engines, they would be ok.

I've raised this subject with diesel owners and to a man, they are adamant that their cars are clean. I reply that they've never been riding a bike or been a pedestrian when their precious (clean!) diesel car has powered past them at full throttle!

If I ruled the world, I'd double the price of diesel - in stages over the next few years. I'd double the VED - in stages too. I'd bring in a scrappage scheme for them with good discounts off modern economical petrol cars, and hybrids and electric too.

I'd set up a scheme where businesses could claim back the excess diesel fuel prices via their tax returns. That way, the cost of transport and deliveries wouldn't be affected.

Sorry for hijacking this thread, but the subject really gets up my nose.

Best wishes,
Mick.

On the whole I don't disagree with you. Unfortunately as it stands it would have to be made alot more cost effective for me to have a petrol car. I've never owned a petrol car.

When buying my 500 I thought long and hard about it. It was the perfect opportunity for me to move to a petrol however after doing the sums it was more cost effective for me to go for the 1.3mjet over a 1.4.

Out of interest what realistic range are people getting out of a full tank of full?

That's a good question.

For me with our 85TA, we are averaging 42mpg. Measured over two years and 10,850miles.

With only a 7.5gal (imperial) tank in a 500, it means on average we get just over 300miles on a tankful.

Our average mpg is low due to the hills round here. Locally, the figure is about 35mpg, but if we go further afield, the average goes up to the mid 50s quite easily. Therefore if I drove further and maybe flatter, we'd get maybe 375 miles per tankful.

Cheers,
Mick.
