Thoughts on this E53 estate!

[sl500amgsport]

Run flats aside, what are the 20s like and what profile / size tyres come on these?

275x30 97Y on rear and 245x35 95Y on front.

The 20s look good with plenty of grip, ride is a little firm over pot holes and uneven surfaces, fine on good A roads...

The standard W/S213 runs very well on 20in wheels in part due to the double wishbone suspension.

I’m stuck with the runflats for a while they are fairly new so even in AMG comfort mode the ride is firm - can’t wait to get rid of them it transformed the ride on the BMW with 19in wheels

These are the wheels fitted to the car:

I thought I’d search out the location of the 12V and 48V batteries this morning. The 12V AMG battery sits in the estate boot under the loading deck and the 48V Li battery sits in the engine bay against the bulkhead on the passenger side both easily accessed. The 12V 70 Amphr battery was sitting at 12.1V so at quite a state of discharge no doubt due to being parked/shunted around on a garage forecourt for over a month so currently on charge with a CTEK.

You need to work on your parking... See if you can get it in the middle next time...

Well the 70 Amphr battery needed over a 6 hour charge with a 7.0 Amp charger it’s not just the tyre pressures most of these car outlets ‘forget’ to check before vehicles leave their premises ‘if it starts push it our the door’. With my low mileage I’m pretty sure this is going to be a regular occurrence (certainly more often than the 212 probably due to an off duty heavier load) I might consider fitting a battery condition monitor

Mine been reading this since I bought it, only 1 day showed fully charged which was after a 120 mile drive...

AGM batteries are built for deep cycles but I don’t think leaving it at 12.1V for any length of time will do it much good hence charging it today. I’ll check the voltage again in 2 months time just to get an idea of where that leaves me with my usage

I’m interested in what the charge rate is in the 48V battery Mercedes Me don’t seem to want to go there perhaps I’m being a bit anal about it but curious nevertheless

Has anybody had squealing brakes on their S213 /AMG E 53?

Mine started squealing a few weeks ago so I took it to the dealer who told me it was a known issue and the front brake pads would need to be replaced, but he added this would not be covered under the warranty as it is a wear and tear issue.

If it’s a known issue I don’t really see the point in replacing the pads with another set of OEM pads!!

 

[DSK]

Are the pads/discs low?

I know on older tech some squealing would be to advise that brakes are getting low, may be they still use that to some degree in addition to electronic bull crap.

No, according to the dealer, there is plenty of meat on the pads. But they think that replacing them will cure the issue. However, I am not convinced.

PS: I have read elsewhere that the problem lies with Brembro brake pads which are Mercedes OEM !!

Might be worth looking at Pagid Pads, used them on my R231 SL and worked well....

Aye, that was the solution for somebody on another forum; ditched the Brembo's and replaced them with Pagid

I wouldn't be surprised if the "fix" of new pads is their way of getting paid to put anti-squeal on the pad mating surfaces.

I'd whip the pads out, clean up the carriers and add the paste myself and refit the original pads

Squealing brakes is a known issue on the W/S213. When my son bought his 16 plate 18 month old W213 220d from a MB franchise on the test drive I noticed the brakes were squealing (this was at 17k miles) so when we sat down to discuss the purchase of the car I threw new discs and pads all round into the equation and one short conversation with the sales manager later this was agreed, looking at the wear on the discs and pads I had the feeling the brakes had been used well, the replacements lasted until he sold the car at 75k miles.

I feel it’s really important to bed the pads and discs in for a couple of hundred miles nowadays the discs wear at a much higher rate than they used to as they are a softer material.

I can’t advise you on whether to change just the pads but it does concur with the experience above and it is a common issue - hope this helps

Think there is an echo in here..

@Blobcat Interestgly enough, the squeling only started after its 'B' service in December; so did they squirt too much brake and clutch cleaner around the brake pads ??

If they washed the car then over enthusiastic use of traffic film remover and intensive cleaner on the wheels can remove it

Just an add on comment to the one I made above regarding charging a 12V battery on a MHEV.

I charged the car a couple of days ago with a CTEK charger on the normal battery setting (not AGM) having already discussed this with CTEK Technical and following their advice. The E53 owners manual states that if a car is fitted with the 48V Li battery the charge should not be above 14.4V as opposed to the AGM setting which is 14.8V and could upset some of the electronics.

Just to satisfy my curiosity I charged a spare 12V battery this morning with the CTEK and set the charger to normal and measured the DC voltage with a multi-meter and sure enough it was 14.4V I then switched to the AGM setting and the reading was 14.8V so the only difference between the settings is a slight increase in voltage - hope this helps it certainly cleared things up for me
